Hi aadil9265711,
Thanks for the post. As you may see my discussion with another developer in this post: Hide "Meeting in progress" notification not working, we have an interface disableShowMeetingNotfication( https://zoom.github.io/zoom-sdk-android/us/zoom/sdk/MeetingSettingsHelper.html#disableShowMeetingNotification-boolean-) that could hide this notification but it only works on Android OS lower than Android P. Unfortunately it not possible to customize this notification right now and we are working on adding interfaces to allow customize this notification.
Thanks!
