I switched away from Google's Messages app due to serious performance issues, but I'm missing some of its features.

One is a Quick Reply button in SMS notifications, which was already suggested 6 years ago (I added 3 votes to it today).

But here I want to request another feature from Messages app. When an activation code/2-factor authorization code/one-time password is received, provide a "Copy" button in the notification and in the chat screen for fast copying of the code. It's super useful!
