If you want to delete the chat records on everyone's computers, I'm sorry, even the horse can't do it unless you have the ability to hack everyone's computers in your group-in that case, you don't have to ask. There is a way-the group space has a chat record function-if you open all the chat records-by default, only the chat records with more than 100 words will be saved, and you can delete them here. That's all. /that's all/that's all
