Download element.io, make an account somewhere. Matrix.org has a bridge for e.g. libera IRC, so you can use it like an IRC client with a free bouncer too for example.

Also since the protocol is http, a friend of mine lets his servers send him notifications about cronjobs by just curling an endpoint. Lots of things you can do with it.

You don't need to use matrix.org to use the Libera bridge. You just connect to #channelname:libera.chat like any other matrix room.
