Chat Reminder

Hello! How are you doing?
The suggestion I have is this

Hasn't it happened to you that you and a friend decide to do something the next day, but you forget?
Wouldn't it be great if there was a "create reminder" button to avoid it?
Well, that is my suggestion, it would be very useful if that option existed, not only to play with a friend, but also to not forget to do some homework, do a group activity, etc.

Please, take it into account, it's just a button and the utility it would have is really wide.

Thank you for reading :)
