Signs of potty training? Help!

What were the signs for your little ones? Right now our 22 months old hides to poop, pulls at his wet diapers, and says poo when he poops and he will grab your hand to get you to his room to change his diaper. I feel like he is really young to potty train but didn’t know what else I should wait for or how to go about it. I don’t want to push him or anything
