How to open a door only if the player has a specific number of points?

I hate to be an ■■■, but I literally have no idea what half of that is xD If you could maybe post screenshots of these things or a step-by-step bulletpoint list on what I need to do, that would probably help me a lot! I am unbelievably new to Unreal (Hilariously, our college tutors are terrible at teaching us how to use something, they themselves often find videos or tell us to, and on this, I could not find a video xD )
