Problem with clarity in EditorInspector subpage

**Your Godot version:**

4.3-beta1_mono (I'm coding in C#)

**Issue description:**

I was reading over the linked page and it says `EditorInspector used in the editor's Inspector dock, use EditorInterface.get_inspector.` which makes total sense, and all, but it also says

`EditorInspector will show properties in the same order as the array returned by Object.get_property_list.` which suggests, that I can use it to make an editor utility similar to the Editor when I make an EditorPlugin and want to have an EditorInspector that shows different properties than the main one, but I wasn't able to make one.

Alright so what I want to know is: As a plugin developer can I actually use the EditorInspector API to make my own EditorInspector or is that purely internal and the page is there to explain to me how to access the built-in inspector?

If I can use it. It would be neat to have an example in the docs telling me how, because I didn't got it to work at all.

If it is for internal use and the only important part for an plugin developer would be the "EditorInterface.get_inspector", than it would be good to to have it somewhat mentioned. (for example. `[...]Object.get_property_list[...] is not actually exposed to Plugin or game development, but an hint to engine developers` )

Edit 1st June:

I wasn't able to figure out how to use it still. I added it as side panel and main panel, inherited it, made a template scene with vbox in it and instantiated it. It never calls back the GetProperties function.

Do I have to call it back from another part of the plugin and implement the parsing and rendering as well? Then I could just use a normal Scroll Area.
