Classroom attendees frontend

[kernicPanel]

Feature Request

With this PR #2461 we retrieve classroom learning analytics from BBB. We want to display it in the front.

BBB displays it like this:

But we want something more like the attendees we have with webinars:

An example of the learning analytics we are retrieving is here: https://github.com/openfun/marsha/blob/master/src/backend/marsha/bbb/tests/bbb_utils/test_get_learning_analytics.py#L32-L133

And this is what we are sending to the front through our API: https://github.com/openfun/marsha/blob/master/src/backend/marsha/bbb/tests/api/classroom/test_retrieve.py#L1320-L1377

Please note that we can have several sessions for a classroom.

Please note that we can have several sessions for a classroom.

How should I present that if there is more than 1 session ? Do I merge the sessions or we separate them ?

[lunika]

If there is more than one session:

• we can add a select box and the user can switch between the existing session. The last session is display by default or
• we can display the sessions in the same page, sorting by session date desc (the last is the first shown)

WDYT ?
