Help adding function for Color3 Wheel Picker?

I've recently found a free gui for a Color3 Wheel Picker, and I was wondering if anyone could assist me in adding a function to it, picking the colour is perfectly fine however I have a datastore system which saves the colour for an automatic character cosmetic script.

What I need to be able to do is load the RGB into the specific function and have it position the colour wheel selector where it would be when you click to select the colours.

Here is the link to the colour wheel: COLOR WHEEL
