Pay with Pix?

I was copying a text from my friend on my A16, and the option to 'pay with pix' came up next to the "copy, paste, select all, etc". I'm not sure what this means, I've never paid money for anything on this device and I'm kind of confused. I haven't given out any information or clicked suspicious links lately. I also don't have a pix account linked to my samsung account and didn't get any alerts about suspicious log-ins or account creation, and I have 2FA enabled. I looked for anything I'm logged into that I don't recognize and nothing has come up. Any kind of explanation for this? I have OCD and things like this make me extremely anxious.
