How do I lock my phone automatically by shutting the folio case

I do no like always on display and disabled it. I want my iPhone 14max to act like my XS max and instantly lock and sleep when I shut my folio case on it. This happens due to magnets or maybe the light sensor I believe. How do I enable this feature again? Please tell me they didn’t remove the hardware for such a simple feature? Please don’t try to encourage me to use always on. Here’s what I want: I want to be able to lock my phone instantly by closing my case like a book. I don’t want to have to push the side button and I don’t want to have to wait for the auto sleep countdown to take effect. Anyone have an actual solution?
