Clearing Dms Button

We probably can't clear dms because let's say for example you said something offensive. You try to clear the whole dm to make you in the clear. Which would erase the evidence. But how about you request to clear dms. Say you click the button to clear dms, not only do you need agree to the erase the dms but you will also need the other person to agree. Basiclly an agreement. As of now there is no way to erase our messages easily which is annoying especially if you want to clear the cringe messages. Just please make an option
