Trigger App Settings, how to perform this function?

Good day.

I'm trying to create a Watch Face Menu in the form of "Trigger App Settings".

I have a couple of questions for you:

1) Is it possible to delegate parameters from the strings.xml file to this Menu, or must it be the jsonData.xml file?

2) What form can I do - delegate a multi-language file to the code?

3) Is there a brief guide - how to do this?

Thank you for your answers...
