Potty training help

We’re on day 3 of potty training and my daughter isn’t going on her urges she kinda still just wets her pants instead and doesn’t let me or her dad know when she needs to go pee she’s peed in the potty the last 2 days and had maybe 1 or 2 accidents but today it’s like day 1 again I really don’t know what else to do…. It seems like she’s not really getting the hang of it. She has to sit 15-20 min on the potty too before she even goes pee and then repeats We let her pick out a sticker to put on her pee pee wall and then a lollipop after and encourage her and celebrate whenever she does go in the potty

Some one please help I’m slowly loosing my mind and feeling extremely discouraged and almost want to stop potty training cause I don’t see any progress
