Keep the Dash to Panel UI Hidden Using Shortcuts

In some applications the Intellihide doesn't work because the app doesn't suport fullscreen (so this option does not trigger):

It's pretty uncomfortable getting interrupted by the Intellihide every time I hover the mouse near the edge of the screen. I've tried manipulating some of the options to keep the panel hidden while I run those kind of applications without full-screen feature.

I came here to ask Ubuntu if there is a method to program or activate a shortcut to keep the panel hidden until I press the shortcut again? (the same way there is a shortcut to hold the panel visible)
Hold the panel visible shortcut in the extension settings:

Edit: No, I don't want to remove the extension. I'm just seeking for a method to keep it hidden at will. I'm going to provide an image of what I mean

Holding the panel hidden (What I need):

Intellihide enabled (what I want to temporally disable using shortcuts)

Edit 2: I achieved recording the Holding the panel hidden by disabling temporally the extension, I haven't resolved yet the problem so I'll start a bounty.
