How to bring back the full size emoji keyboard using magic keyboard’s globe key?

I want to bring back the full size emoji keyboard. It’s a hassle using the little pop up emoji keyboard because I can only pick one emoji and then it disappears. Unlike the language keyboard, I can’t pinch the emoji keyboard to full size. Please help. I already restarted my iPad and detached it to the magic keyboard but still the same small size after attaching it again.
