Additional meeting and call-related features and issues within Microsoft Teams for Education
Hi Bridget, hope you're doing well. I’m Ian, an Independent Advisor and Microsoft user like you.
I'm sorry to hear about this issue.
Currently, there is no automatic way to notify the meeting organizers that the meeting is about to end, and its time to wrap up the discussion.
This feature is currently in progress and the initial release would be on Dec, 2020.

With this new end-of-meeting reminder, Microsoft aims to address this issue by showing reminders on top of the meeting window, making them much harder to miss. Microsoft Teams will automatically issue a 5-minute warning when the meeting is nearing a close – it will be triggered for all scheduled private, and channel meetings.
This is a user-to-user support forum and I am a fellow user.
I hope this helps, but please let me know if you need anything else.
