[RheingoldRiver]

Is your feature request related to a problem? Please describe. N/A

Describe the solution you'd like I HAVE NO IDEA HAHA how do you even link to matrix chats

Describe alternatives you've considered good luck

Additional context If the Element app or another popular matrix app is installed, would be real neat if you could "open space in X app"
