Language Server Protocol: Get Symbol Information of inner functions/classes

What I want

I'm searching for a command in VSCode (a la vscode.commands.executeCommand(...)) that returns symbol information (outline) of inner functions/classes of a function/class.

Example

A command like vscode.commands.executeCommand('vscode.??', Range(2,6)) on

1  def foo1():
2     def innerfoo():
3        print("hello")
4     def innerfoo2():
5        print("world)
6     innerfoo()

should return an array with innerfoo and innerfoo2.

What I've found

The command vscode.commands.executeCommand('vscode.executeDocumentSymbolProvider') will provide 1st-level symbol information for the whole document. E.g. in

class MyClass:
  def foo(self):
    pass

only MyClass is found

This information is hidden inside the children property of DocumentSymbol (returned by vscode.executeDocumentSymbolProvider):

let symbols = vscode.commands.executeCommand ('vscode.executeDocumentSymbolProvider');

console.log (symbols[0].children);

I write 'hidden' because children does not show, if you simply run console.log (symbols); in the above code.

There's no API like that. Language support is self contained and usually does not provide its information to the outer world.

You would instead have to create your own parser, which processes the code to find symbol information.
