Shopify Security Issue Fix

Someone tried to take over my Shopify store yesterday, and I need someone to fix the security issue immediately. The task involves undoing any unauthorized changes and ensuring the store is secure. This is an urgent matter that requires a freelancer with expertise in Shopify and security. I need that fixed and I need whoever's going to do this for me to just finish the little bit of what I haven't been able to because I wasn't aware of it out of ignorance so I apologize in advance I didn't know you had to plug this into that and that into this and I just was unaware but I've done most of the work thanks to Claude and the other AI's. I had to do it that way because starting a business and not having any money up front the way I've done this is a hell of a story but the brand is the thing that when you see it you'll understand what I'm talking about as far as why someone tried to take it. I've attached a couple of pictures from my store at the bottom
