Override Roblox Mouse Sensitivity in FPS?

I’m working on an FPS and I thought it would be really cool if the player had the option to override their roblox sensitivity and use Source Engine sensitivity. I’m not sure how Source sensitivity is calculated or how to even adjust the player sensitivity in Roblox without them manually going in their menu and changing it. I really struggled to find much information on this topic so any help would be cool and I assume it’s possible because some FPS already let you change your sensitivity in game (like Phantom Forces).

The only thing I’m aware of is utilizing the MouseDeltaSensitivity property of UserInputService
