I have been learning the Godot engine, and want to export a test game to itch for web. I finished everything, but am stuck with a blue loading bar that doesn’t fit my style! I want to change the color of the background in the loading bar and the actual progress bar. I use Godot 4.3.

Edit: I learned there is a Godot Doc on it (Link), but it requires JavaScript skill I don’t have. Can anyone help with that?
