Building, integrating, or customizing apps and workflows within Microsoft Teams using developer tools and APIs
Hi Ram,
I'm Nik, an independent advisor here to assist you with this.
Thanks for posting your question on the community forum.
MS Teams allows the meeting organiser to download the attendance list anytime during the meeting, not after the meeting. That said, it completely depends on when the meeting organiser downloads the attendees.
If you were in the meeting when the attendance download happened then, you'd be marked as attended.
