我尝试在访问令牌过期时向服务器发送刷新令牌并接收新的访问令牌，但代码无法正常工作。
刷新令牌类

class RefreshToken(): Authenticator {
    override fun authenticate(route: Route?, responsee: Response): Request? {
        if (responsee.code == 401) {
            lateinit var loginRepository: LoginRepository
            lateinit var bodyRefresh: BodyRefresh
            lateinit var access: StoreAccess //datastore for save token
            lateinit var newAccess: String

                CoroutineScope(Dispatchers.Main).launch {
                    access.getUserRefresh().collect {
                        val refresh = it.toString()
                        bodyRefresh.refresh = refresh
                        val response = loginRepository.RefreshAccess(bodyRefresh)
                        if (response.isSuccessful) {
                            access.saveUserRefresh(response.body()?.access.toString())
                            newAccess = response.body()?.access.toString()
                        }
                    }
                }
            
                return responsee.request.newBuilder().header("Authorization", "Bearer $newAccess.toString()")
                    .build()
            } else {
                return responsee.request
            }
        }
}

API服务

@POST("token/refresh/")
    suspend fun refreshAcssec(@Body refresh: BodyRefresh): Response<ResponseAcces>
