How can I invoke foreground xaml in a backgound xaml using windows framework?

Yeah! Thanks! You remind me of requesting orchestrator api trigger which is an useful way and can pass parameters as well. By the way, I posted another help on this forum few months ago. And I really like api trigger feature.
