Separate app lock for each app

I am using Samsung phones for very long time. Starting from Samsung Galaxy A7, Note 10 Plus, S21 ultra and S23 ultra. And I also to promote it to my family and friends. But some iPhone features always made me jealous separate lock is one of them. I really wish that I could have some featured on Samsung phones. Like a little someone use my phone for Make a phone call or something else. And after that the person start opening my social media apps and others. And I really hate that. I think if Samsung wants to compete apples privacy. They should provide  feature where every user can lock their each app separately.
