Delete sender's messages PLEASE!

I've been using Discord for a long time. And I text a lot in it. Discord doesn't have a option to completely clear a chat or delete a sender's messages (at least just for me). For example, when receiving unwanted messages from bots, I want to delete the certain messages I don’t need, and continue to use the bot, I don’t want to block it, etc. Any messenger has this feature. PLEASE add a function to delete sender messages.
