How do I change the limit of the zooming?

I'm working on a FPS game, I just made a weapon selection, but the FPS script I currently added does not let players click the class rank they want to use.

Here's the FPS GUI script I use:

game.Players.LocalPlayer.CameraMode = Enum.CameraMode.LockFirstPerson

I couldn't find anything on the Roblox wiki, can it be scripted with the script above?

You could wait until they select their class to change the camera mode.

Most commonly by using Player.CameraMinZoomDistance and/or Player.CameraMaxZoomDistance. I've heard this is still glitchy, so please be aware it might not work due to roblox. Also, I've heard this does not work in studio mode, and put it inside a LocalScript

game.Players.LocalPlayer.CameraMinZoomDistance = 0 --Put the Minimum amount the player can zoom in here
game.Players.LocalPlayer.CameraMaxZoomDistance = 0 --Put the Maximum amount the play can zoom here
