I do that a lot lol :3 for me there's a lot of reasons (anxiety, drained social battery, feeling extra dysphoric about my voice etc.) but I still like hanging out with friends together even if im not necessarily talking :3 I guess it's kinda like parallel play.. though I do usually interact more when playing games online than one would do with that, just not verbally. But there's text chat, or helping my friends/working on a task together etc.
