Roblox Weapon Kit Shoulder Camera / Mouse Lock Fix

I was planning on using Roblox’s Weapon Kit into my game as it works fine and isn’t that bad.

My Question Is:

Can I modify this kit so that the shoulder camera isn’t constantly set how it is below and fix the mouse lock?

Ideally I want it to be third person where you can shoot with your cursor, and then players can do first person or shift lock/mouse lock if they want to as well.
I have found other posts on here and tutorial videos but all are outdated as far as I am aware.
I have tried messing with this but I am not that great at scripting so I didn’t get very far.

If anyone knows anything I could do to achieve this with the Roblox Weapon Kit, any help is appreciated!

(Or… Would I be better off just using a different system for weapons or having someone make something for me?)
