Does video/voice work? Can you screen share? Can I share files? All these bridges seem fine for basic text but modern chat programs do a lot more these days and I personally can't see the point without 1:1 feature parity. This seems doubly true for a service like Teams versus something like Discord where Teams is going to be installed and configured by a central IT team for all users. I know a lot of this falls on companies building their own proprietary, non-interoperable messaging platforms and this is an effort to unify them and I don't mean to shit on those efforts but it just seems like it's a lot of effort for becoming a third class citizen when interfacing with those platforms.
