Kegels? HELP

Yesterday my husband made me laugh and I slightly peed myself, so I want to try some kegels for this. However, when I’ve tried in the past, I can never figure it out! I’ve tried to stop my pee flow, but I need tips. I feel like I’m just wasting my time because I can’t do it right! Any tips? I feel like I can’t find that muscle.

(I do have a set of kegel balls if I need those)
