Accessing Meeting Participant List via a Teams App (not a Bot)?

Hi everyone,

I'm currently working on a Microsoft Teams App (not a bot), and I'm trying to figure out if it's possible to programmatically access the participant list of a meeting - either during or after the meeting - directly from within the app context.

Here are my specific questions:

Is it possible for a Teams app (not a bot) to access the list of meeting participants?
If yes, what are the required conditions (e.g. permissions, app manifest settings, API endpoints, etc.)?
Are there any restrictions regarding the app context (e.g. does it have to be running in a meeting side panel, meeting stage, etc.)?

If anyone has experience with this or can clarify whether this is possible at all, I’d greatly appreciate your input!

Thanks in advance,
Michael
