We are getting the following crash (in production) whenever a user attempts to share their screen during a meeting. The crash is 100% reproducible.

Which Android Meeting SDK version? 7.0.0.38589
To Reproduce(If applicable)
Select Share > Screen > Share entire screen
Screenshots
(When attempting to add screenshots, I get an error message that I can’t attach media items.)
Troubleshooting Routes
We’re not doing any client-side manipulation of screen sharing.
Smartphone (please complete the following information):
~82% Samsung phones, 11% Motorola, and a handful of other manufacturers. Approximately 67% of those users are on Android 16.
Additional context
We have several thousand of these crashes in the past couple of months, but have been unable to find an issue with our integration.
@ChrisM Thank you for posting on our dev forum. We might need more information to investigate this crash. Had you set it enableGenerateDumpto true when initializing the SDK? Also, is there more crash dumps other than the one you provided? If there’s more crash info, please share it with us. Thank you
I enabled that flag and did the repro steps again. This is what it logs with the flag enabled:

Looks like FOREGROUND_SERVICE_MEDIA_PROJECTION is missing; if I explicitly declare this permission in the manifest then screen sharing works.
Is there a way to disable the screen sharing button for users in a meeting? I ask because I am not keen to go through the Google Play approval process for adding the missing permission.
