Friend invites should work with dedicated servers too

It would be cool if the new friend list also supported inviting your friends to the dedicated server you are currently playing on.
Of course you can copy/paste and share a server address via Discord or similar. But being able to directly invite friends in-game would be a nice QoL feature that seems reasonably easy to add.
It would also make finding new servers to play on rely less on external server lists.

This could work very similar to the already existing transfer packet. Maybe the MOTD of the server a friend is currently playing on could be shown in the friend list, on hover over the friend or similar.
