For the “Display prompt” workaround: You can use XRunAndWait + VBS file to show an input box that is on top of everything:
Dim sInput
sInput = InputBox("Enter number")
MsgBox "You entered:" & sInput
' Send exit code to UI.Vision
WScript.Quit sInput
Inside your macro you get the return value (exit code) with ${!xrun_exitcode}
