Importing custom resource type (html and css)?

Godot Version

4.3

Question

I imported someone else’s Android/Quest project (Open Saber), and the project has an html and a css file in one of the script directories. These files are accessed by the code as “res://zzz/yyy.html” and “res://zzz/yyy.css”. However, these files don’t show up in FileSystem browser in Godot, and they don’t get exported to the apk (they don’t appear in android/build/assets/zzz, and the game can’t read them).

I can’t figure out how to get Godot to include them as resources. (I am new to Godot as may be obvious.)

My temporary work-around was to add a fake .theme extension to the filenames, and now they get exported to the apk. But this is clunky, and obviously it somehow worked for the project I am trying to build (and modify).

In the input field “Resources → Filters to export non-resource files/folders” (in the Export window) you can add more file types that you want to include.
