App Permissions pop-up for Location Services never shows on screen recorded video

I know this is not a programming question but thought I would give it a try anyway. I have been unable to get a app screen recording to show popup in recording that user gets when starting app for first time. I can see the pop up clear as day but it never shows on recording.
Is there a trick to get this pop up to show? App Connect says it is required in the video...so kind of stuck. I have tried QuickTime Player, iPhone screen recording, etc to no avail. Running Catalina v10.15.6. Thanks!

You can set up a BroadcastReceiver that will receive any camera button presses if that's what you want to do.

iOS - Access output audio from background program

Scenario: My app is running in the background. An iPhone/iPad user launches the iPod app (or Pandora or another program that plays audio) on their device and starts playing music. My app detects that that music is now playing, and records or in some way does things with the current playing audio (like stream it to a server), all while still running in the background.
Is this possible? Can anyone point me in the right direction in the SDK on how to do this?
You can't do this. And that is that.

Closing iPhone Video Player using Javascript

I have a web page with several html5 tags, offering users a number of posters/thumbnails for videos they can choose to play. When a user touches one of the them the iPhone video player opens and the video plays. I want to be able to automatically close the video player after the video has finished and return the user to the thumbnails.
I have set the event listener for the "ended" event and I can detect that the video has finished, but I can't figure out how to close the video player and return to the thumbnails. It just waits for the user to touch the "done" button. Is there any way of doing this in Javascript??
jQuery -
$('video').get(0).webkitExitFullscreen();
Uncertain what iOS version this was supported. See The correct method is webkitExitFullscreen. See https://developer.mozilla.org/en-US/docs/Web/Guide/API/DOM/Using_full_screen_mode for full support
