How Add shortcut [BackSpace] to back folder on Nautilus?

I want to add shortcut and press backspace button to return to the previous folder whilst browsing the Home folder.

I use Gnome 40.1 - Fedora 34. Some can help me ?

You can navigate with alt + left arrow or alt + right arrow and I think this is system-wide (works in Firefox as well) but I don’t know how to change this. Just checked Setting → Keyboard → Customize Shortcuts but couldn’t find anything unfortunately.
