How to toggle between 2 HUD widgets?

I have camera toggle on keyboard key T. It toggles between First Person view and Third Person view. I wonder if it is possible to switch HUD depending on what camera is active.

I want (only) HUD widget 1 to be active when I am in FPS mode, and (only) HUD widget 2 to activate when I am in 3rd person view.

After some time… I managed to get it to work. (All by myself #Proud)
But, because I did it myself, there are probably 20 things that could had been done in a much better way.

Anyway, here is the result of what I did.
