riddle time my fellow degenerates

so supposedly when u die u appear before 2 doors ( the door to heaven and the door to hell ) and in front of each door is a twin the twins look exactly alike but one of them is an angel and one of them is a demon
the demon will always lie to u and the angel will always tell u the truth
you get to ask each one a question to find out which door is which
wut question do u ask each one
we're probably all going to hell here but just in case this is a thing stick around
:) me xian xian will revealeth the awnser eventually if no one gets it
