我尝试打开另一个对话框片段，代码如下：

private  fun showList() {

    val job = Job()
    val scopeMainThread = CoroutineScope(job + Dispatchers.Main)
    val scopeIO = CoroutineScope(job + Dispatchers.IO)

    val adapter = ServerListAdapter()
    val recyclerView = binding.rvConnList

    binding.rvConnList.addItemDecoration(
        DividerItemDecoration(
            activity,
            DividerItemDecoration.VERTICAL
        )
    )

    recyclerView.adapter = adapter
    recyclerView.layoutManager = GridLayoutManager(activity, 1)

    val serverViewModel= ViewModelProvider(this)[ServerViewModel::class.java]
    scopeIO.launch {
        val x = serverViewModel.getAll()
        scopeMainThread.launch {
            activity?.let {
                x.observe(it) { s ->
                    s?.let { it ->
                        adapter.setData(it)
                        adapter.onItemClick = {

                            SyncSovEntryFragment(Date(), it).apply {
                                setListener { _, year, month, dayOfMonth ->
                                    Toast.makeText(requireContext(), "Set date: $year/$month/$dayOfMonth", Toast.LENGTH_LONG).show()
                                }
                                activity?.let { it1 -> show(it1.supportFragmentManager, "MonthYearPickerDialog") }
                            }

                            Toast.makeText(activity, it.database, Toast.LENGTH_LONG).show()
                            dismiss()
                        }
                    }
                }
            }

        }
    }
}

我正在尝试打开另一个对话框片段，是否有其他方法可以在对话框片段中调用supportFragmentManager？因为以下代码不起作用：
活动？.let {it 1-〉show（it1.supportFragmentManager，“月/年选取器对话框”）}
谢谢你，谢谢。
