Help on potty training!!

How to get my toddler to actually use the potty? She isn’t afraid of it. Today we’ve been diaper less she’s peed 3 times on the floor l, the couch and her undies. Idk what to do I’m here with her next to her but I can’t predict when she needs to go. HELP! She’s almost 2.

Edit: Thank you everyone for your responses, she has Hiden to pee or poop since a few months and she now has remove her diaper on 3 occasions I bought undies when I notice that and she loves them and now she screams and cries when I put diaper on her! She wasn’t doing this before but we made a trip and maybe she started hating it because of the heat there? Honestly I have no idea what I’m doing lol.
