✅ Unity Super Mario level assistance

Hello, I am Ember. I will make this as brief and concise as I can. I am currently working on a task in Unity. The main goat is to implement a P switch into the level through the item box. The instructions of the Pswitch are shown in the attached text file (it's a bit of a read, I'm sorry 😓 ). As of right now, what I have is the whole level's scene built as well as the prefabs like the breakable blocks, coins and the item box included as shown in the attached image of my work. The only thing I have left to tackle is the P switch implementation, which has had me completely stumped. I have gotten as far as adding a PSwitch enum to the itemBox code, but that's as far as I've gone. I need urgent help with this, and would absolutely appreciate it if anyone could assist with this I've attached a video of how the level is supposed to work and a picture of what I currently have now.
