Potty training

Any miracle tips or tricks to potty training? I’ve been putting my daughter on her potty every 15-20 min today and she wont pee. But then just now, of course, she peed in her diaper (in between the 15-20 min thing). I even told her she’d get chocolate if she went in her potty! She’s 2 years old, talks a lot, can tell me when she has pee or poop in her diaper. I’m so tired of diapers and also hoping she’ll be done with them by the time her new sibling is born (in June). 🤔 help
