Is possible to get the thumbnails from the different files and use them as an texture? For example the scenes.

As far as I know the thumbnails for the files are stored in %temp%/Godot (Directory for temporary files depending on your OS) in the format resthumb-{res_hash}.
The res_hash is defined in the import file of every resource.

If you read the import file of the resource you want and are able to navigate to the temp directory you would be able to load that file and use it as a texture. But navigating to the temporary folder could be a problem and is already a feature proposal:

It would be useful to have `temp://` as a data path option (like `res://` or `us…er://`). This would link to a directory whose files would be wiped after the engine is closed. This would allow for temporary file storage without the need for the user to manually clean up the directory themselves, along with allowing them to not need to figure out these temporary file paths themselves.

Also I dont know when these thumbnails are being created, so the idea could turn out as unstable.

Looks like get_editor_interface().make_mesh_previews() creates previews for editor code so you could use that to generate icons, save them, and then use them in game. You may need to search your scene’s node tree for a mesh if it’s not the top-most node.

I also found someone wrote code to do it at runtime, but I have no idea whether it works. GODOT 4: Render a scene to texture (for icon or 3D scene in UI) ($2323028) · Snippets · GitLab
