Teams attendance report in online classes for business

Hello,

How could I obtain an attendance report for an learning company that use Teams for online classes?

The problem is that I cannot use the https://support.microsoft.com/en-ie/office/download-attendance-reports-in-teams-ae7cf170-530c-47d3-84c1-3aedac74d310 option because only the trainer is "invited". The students receive the meeting link by and automated message from CRM application, so they are not created as guests.

The current attendance report shows just a blank table because of this setup.

Other Teams add-ons like "Attendance Bot" cannot be used because the students are not part of the company.

To create a team for each class is not an option because of the "administration" process that would render it impossible.

One option was using Power Automate, but Teams connector have only the option to "Create a Teams meeting" - once created cannot be modified to automatically add the students to that meeting.

So, could have a more "reliable" (and automated if possible) attendance report in Teams rather than a simple form in MS Forms that students have to manually complete at each day they attend? 

Kind Regards,

Lucian
