How would I make it so when scrolling on a scrollingFrame it doesn't move the camera?

I have looked at this already but the answer that was given I believe was old and doesn't apply to the current Roblox updates. I have a feeling how it would be done is setting the CameraMinZoomDistance and max distance equal to the same thing when the player hovers over the frame, but I can't figure out how to get the value of the distance. On the script that was given, he wrote it in pseudocode which said:

Pseudocode:

local camDist = (Cam.CoordinateFrame.p - Head.Position).magnitude

However, I simply can't figure out how to get the cameraDistance or any other way that might work. Any suggestions?

EDIT: This has to be done in a LocalScript as I'm working with GUIs.
