Using pytest-bdd with the JUnit argument to produce a nice JUnit XML report.
I then use a cURL command to import the test to XRay, the Atlassian Jira extension.
Jira is running on a server running on our network (not cloud). So I am using something like:

curl --location -X POST "https://jira.nayax.com/rest/raven/1.0/import/execution/junit?projectKey=XXX&testPlanKey=XXX-255" -H "Authorization: Basic Z3VxxxxxxzJMaxxxxxxxxx" -H "Content-Type:multipart/form-data" -F "file=@\"reports/results.xml\""

What I get are tests with names exactly as expected given the XML file. Example fragment:

<testcase classname="tests.step_defs.test_visitor_page" name="test_create_new_user[110-201]" time="1.125"/>
        <testcase classname="tests.step_defs.test_visitor_page" name="test_create_a_package[110]" time="0.306"/>
        <testcase classname="tests.step_defs.test_visitor_page" name="test_search_user_by_first_name" time="0.700"/>
        <testcase classname="tests.step_defs.test_visitor_page" name="test_scan_nfc[110-10001-TYPE_2]" time="1.399"/>
        <testcase classname="tests.step_defs.test_visitor_page" name="test_get_settings" time="0.669"/>
        <testcase classname="tests.step_defs.test_visitor_page"
                  name="test_get_redemption_machine_for_this_location[110]" time="0.680"/>
        <testcase classname="tests.step_defs.test_visitor_page" name="test_add_free_credits[110]" time="0.766"/>
        <testcase classname="tests.step_defs.test_visitor_page" name="test_buy_credits[110]" time="0.708"/>
        <testcase classname="tests.step_defs.test_visitor_page" name="test_add_free_tickets[110-yes]" time="1.051"/>
        <testcase classname="tests.step_defs.test_visitor_page" name="test_add_free_tickets[110-no]" time="1.034"/>
        <testcase classname="tests.step_defs.test_visitor_page" name="test_purchase_group_package[110]" time="0.968"/>
        <testcase classname="tests.step_defs.test_visitor_page" name="test_get_user_history[110]" time="0.676"/>
        <testcase classname="tests.step_defs.test_visitor_page" name="test_delete_billing_record_from_history[110]"

So you get Jira XRay items named:

Is there some decorator or other device I can use to get the Summary fields below (names of the items, like test_buy_credits[110] ) to be something like:

• Create New User
• Create a Package [110] etc.?

Writing an XSD and using an XSLT transformation would probably work, but would be great if there's a simpler way.
Per request, here's are some tests:

@allure.step
@given('Location ID is "<locationId>"', target_fixture="location_id")
def location_id_is_locationid(locationId):
    """Location ID is "<locationId>"."""
    return locationId

@allure.step
@when('I create a package', target_fixture="package_response")
def i_create_a_package(location_id):
    """I create a package"""
    package_response = Package().create(location_id=location_id, session=s)
    return package_response

@then('package is created')
def package_is_created(package_response):
    """Package is created"""
    assert (package_response.status_code == 200)

In answer to the question about my test_ functions, I have to admit that I am pretty new to this, so I only have the given-when-then implementations.
Here is a piece of my feature file:

Feature: Visitor Page
  Scenario Outline: Create new user
    Given Location ID is "<locationId>"
    When I create a new user
    Then call is successful
    And return code is <returnCode>

    Examples: User parameters
      | locationId  | returnCode  |
      | 110         | 201         |

  Scenario Outline: Create a package
    Given Location ID is "<locationId>"
    When I create a package
    Then package is created

    Examples: Package parameters
    | locationId |
    | 110        |

  Scenario Outline: Purchase package
    Given a user exists at "<locationId>"
    And I have created a package
    When user purchases the package
    Then the user will have the package

    Examples:
      | locationId |
      | 110        |

  Scenario: Search user by first name
    Given I have a first name and nfc tag
    When I search for user
    Then I retrieve user details

  Scenario Outline: Scan NFC
    Given a user exists at "<locationId>"
    And box ID is "<boxId>"
    And tag type is "<tagType>"
    When I scan the NFC
    Then nfc tag is scanned

    Examples: NFC parameters
    | locationId | boxId | tagType |
    | 110        | 10001 | TYPE_2  |

  Scenario: Get Settings
    Given I am logged in as an employee
    When I request settings
    Then I get settings
