i accidentally created a 3 person group chat, me being the 3rd member, when I was sending my lover a song from spotify somehow lol. It was an actual accident with a literal random person in our new group chat. I need to delete this group chat but the “leave this conversation” button when you look at the group & its details & settings is dark & not accessible currently & is absolutely & entirely useless. The others say to just mute the chat but id rather not HA HA so please help me ❤️

Delete the group thread, so long as no one responds to that thread there will be no issue.
