Potty training!!

My daughter has shown signs of being ready to potty train since 12 months she is now 3yrs.I can say with work and life I just did not invest time with her. She uses the bathroom at school (I think bc they have mini toilets and sinks) and she will use it at her dad’s but she refuses to go at home unless I am mad at her…. I don’t know what methods to use or take. I’ve tried rewarding I’ve tried sitting with her I’ve tried it all. If you have any recommendations or what worked for you I would love to hear them!
