[Python] How to automatically generate python type annotations (with GitHub Copilot)?

I would like to automatically generate type annotations for python function arguments for a whole file. If I ask GitHub Copilot to do so, it only outputs parts of the file, e.g. the function headers:

def _draw_io_url_with_encoded_xml(xml_string: str) -> str:
...

def _demo_draw_io_xml_string() -> str:
...

def _bus_style() -> str:
...


That makes it hard to apply the suggested changes.

On the other hand, if I ask GitHub Copilot to print the whole file content, it reaches its output limit.

=> What is the best way to generate type annotations for an existing python file?

• 
  Can I tell GitHub Copilot to somehow directly change the content of the file at the related positions instead of printing it in the chat window? (I could check the changes using version control.)
  
  
• 
  Is there an improved auto-fix tool based on GitHub Copilot, that is able to fix corresponding ruff warnings for missing type annotations?
  
  
• 
  Even other strategies that could help?
