Hi @Rohan Jingar
Thanks for reaching out!
As far as I know, there is currently no way to check the meeting status (start, end or in-progress) through the graph API, only the status information of the attendees can be retrieved.
I suggest you submit a user voice on this so that Microsoft releases this feature as soon as possible, and I will also vote for you to increase the priority of this request.
Hope this helps.
