I’m assuming you’ve already enabled early access (thank you for the support! 😊) by entering the password, unlocking that setting.
GDScript support is provided only by the “godot-tools” extension, not by “Godot Files”. So, unfortunately, when you click it from GDScript, it will use their own viewer (which only supports English). If you click from a language provided by Godot Files, like .tscn, .tres, .godot, etc., or if you open it from the command (e.g. with CTRL+F1 on Windows/Linux) then it will use the setting for the specified viewer (and language if you enabled early access). If you’re on VSCode, CTRL+F will work on the webview viewer (to search e.g. a class name).
Sorry if this wasn’t super clear in the README, I’ll update it for the next version.
I’ll see if there’s some workaround to this limitation somehow, but as far as I know, I’m not able to make it work from GDScript unless I were to support GDScript myself (not going to happen anytime soon) or overwrite their viewer (which would remove your option to use it).
The “godot-tools” extension would be able to use a viewer from “Godot Files” if they were to implement it themselves, (e.g. by checking this setting on their extension too). You might want to open an issue in their repo to ask for compatibility, maybe they’re willing to implement it? They would just need to call the URI for my viewer in a similar way that I call theirs.
Don’t hesitate to ask if you have any other questions! 🙂
