Hey @nizamani987,
Thank you for following up on this! Currently, we don’t have a method to change the view that a participant is using automatically. If you would like this feature to be considered for a future release, I recommend posting in the #feature-requests category.
When it come to using Gallery View on MacOS, what browser are you using? Please see our section on Gallery View Browser Support
Let me know if that helps.
Thanks,
Max
