Edit: it's definitely jitsi in Matrix, this is what we were presented with for our 3 way (successful) video call, with screen sharing:

Was just stock cloudron matrix, using the stock cloudron element web client on the customer side of the call.

We could not do a successful 3-way video call with this same customer, on the same browser, using the stock standalone cloudron jitsi instance.
We're on cloudron 7.2.5
