Hi @MAGNUS1 ,
This is something you'd need to talk to your school's support team about. Unfortunately, all of the tools you listed (Kaltura, Zoom, and MS Teams) are external to Canvas, so even though some members in the community here might have some experience with those tools, they are going to be configured different for every school and it will be very hard for us to provide help. Hopefully your school can help get things sorted out for you.
I apologize that we in the global community can't give a much better answer than this right now.
