How to remove your contacts from Gas app polls?

how to remove iPhone contacts from gas app so here you see the gas app and when you just create an account uh yeah there are like your iPhone contacts displayed instead of your classmates sometimes or something like that and why is that happening because you need to go in the top left and add your friends from the school or their friends or friends um and then yeah if you do that if you have four or more friends from your school then um your iPhone contacts will be removed and you won't be having displayed them there is no option to turn off contacts or anything like that so you just need to have four or more friends on Gaza app and then your phone contacts will be disabled that's what I write on their support page
