My experience is that people will be happy to use other things if you just ask them to, and have a ready-to-go solution on hand.
Just say "teams doesn't work well on my computer, it's very poorly made. Can we use jitsimeet? It's much easier for me." and them drop them a jitsi link without waiting for their response.
Teams is the official video chat at my company, I've been successfully ignoring that for more than 2 months now. At this stage, jitsi usage is starting to spread to other teams.
