2FA Codes

Rather than having 5 different apps open on macos, I have started using beeper. Everything seems to work as expected except for 2FA codes. In google messages when a 2FA code arrives, you double click on any number (even if it is followed by a period) and it chooses just the number. In beeper, it grabs the trailing period too.

Example would be something like this:

Your code is 123456.

Is there a way to remedy this?
