Hiding a control on a form

I didn't think I'd run into so much trouble trying to simply hide a control on a form.

I'm using the UI

I'm tasked with hiding a toggle switch on the 'Accounts Receivable Parameters' form

I was going to use a new role, and assign the privilege directly to it

I've been fooling with adding references to my role, adding form names, control names..

I can see the form name, and the control name..

I just don't seem to be hitting on the right combination of  steps to tell D365 to: "hide  this control, on this form"

any help/direction is greatly appreciated..
