Frying/heating hamburgers in air fryer?

Hi,

Wanted to ask if I can air fry already done burger patties bought from a store? You know, the one in packages. I'm asking because I saw some people, in different subs, saying it's not worth it because they will lose taste. Is that right?

Second question - what about heating cheeseburgers (buns + patty + cheese), from package also bought in a store. Normally I was heating them in a microwave (you can do that) instead of oven because I do not have one, but is there a possibility to heat them in a air fryer or should I just stick to the microwave?
