If you guys look at your emoji wheel, at the bottom of it there is a button where you can scroll through more emojis while your playing. For PSN players you scroll with L1 and R1, for Xbox I think it’s LT and RT but I’m not sure. As for PC players I don’t know, maybe W and E or something like that. Choosing emojis in your profile is still useful as you can input them quicker since it will be the first ones you see when you open up the emoji wheel.
Just wanted to point that out!
