How do I destroy the hidden wall revealed by the UV light?

[[|·Tyl_Jayd·|]]

Hey there, title as question. Couldn't figure it out and got killed for it so just wanted to know how to do it. Or Did I need to find the magic bag and burn it to break the hidden wall?
Thanks.

You break the wall by using the Sledgehammer tool on it. Which means you need to buy one (costs 500 money) and bring it, then hit the wall in question with the Sledgehammer. Do note that you need to specifically hit the glowing cracks of the wall in order to break it. Just hitting the wall over and over again will not work. You may actually need to crouch to hit lower situated cracks.

The bag will be in the room behind the wall and needs to be burned in the fireplace after you picked it up (it will not occupy a slot in your inventory).
