What would happen if you feed an African Grey a Carolina Reaper pepper?

I read that parrots don’t have the receptors for spicy food, so they have a high tolerance to it. However, the Carolina Reaper is the 2nd spiciest pepper in the world with an average scoville heat unit over 1.6 million. I don’t own any parrots and this comment is not meant for malicious intent. Just genuinely curious.
