I usually mute everyone on the other team at the beginning of the game in order to not be distracted by emotes etc. but I noticed recently that when I do this the other players unfortunately becomes muted after the game is over too.

I noticed that there is now a "mute" button in the pre-game lobby, but I did not see any "mute" button in the post-game lobby.

Is there a way to remove the mute from players (a chat command etc.) without having to get into another game with them again?
