I would like to request adding support for the app lifecycle events for the MeetingStage context as well. Our SPA would benefit a lot from the start up faster launch speeds when the app is already loaded.
Furthermore, we have a specific use case where we would like to save information from the meeting stage when the stop sharing button is clicked. We were originally hoping to use the registerBeforeSuspendOrTerminateHandler functionality to accomplish this.
As documented here it is currently not supported https://learn.microsoft.com/en-us/microsoftteams/platform/tabs/how-to/app-caching
Let me know if anything needs clarification.
Thanks!
