Can the server support custom code prompts?

[wrf1998]

I am currently using the python server in the example, and I find that its code hints only support the data provided by pyright, but I have some packages that are internal to the company, and I want to be able to hint and hover the mouse to see some specific information about the package, etc. How do I need to modify my server side
