First Check

• I added a very descriptive title here.
• I used the GitHub search to find a similar question and didn't find it.
• I searched the Typer documentation, with the integrated search.
• I already searched in Google "How to X in Typer" and didn't find any information.
• I already read and followed all the tutorial in the docs and didn't find an answer.
• I already checked if it is not related to Typer but to Click.

Example Code

import click
import typer

app = typer.Typer()


@app.command()
def top():
    """
    Top level command, form Typer
    """
    print("The Typer app is at the top level")


@app.callback()
def callback():
    """
    Typer app, including Click subapp
    """


@click.command()
@click.option("--name", prompt="Your name", help="The person to greet.")
def hello(name):
    """Simple program that greets NAME for a total of COUNT times."""
    click.echo("Hello %s!" % name)


typer_click_object = typer.main.get_command(app)

typer_click_object.add_command(hello, "hello")

if __name__ == "__main__":
    typer_click_object()

Description

The code above from the Including a Click app in a Typer app tutorial works fine except pyright complains about typer_click_object.add_command(hello, "hello")

Diagnostics:
1. Cannot access member "add_command" for type "Command"
     Member "add_command" is unknown [reportGeneralTypeIssues]

Where do I find the definition for .add_command()?

My editor (nvim) can't find the source for it (works fine with other methods such as .get_command()) and searching the repo only yields that method in the documentation

I've also checked the source for the click.Command class but obviously that doesn't contain the method either

Also, is there an easy way to replace the use of click with typer? The largest issues I currently have is that the hundreds of @click.option() lines and the use of def main(**kwargs) have to be refactored since many functions in the program I'm fixing are simply passing kwargs around
