How to set minimum and maximum length of a string argument?

I have this so far:

@app_commands.Argument(
  username={
    "min_length": 3,
    "max_length": 22
  }
)
async def inv(interaction:discord.Interaction, username:str):
  # code

But it gives me this error:

Traceback (most recent call last):
  File "main.py", line 69, in <module>
    @app_commands.Argument(
TypeError: __init__() got an unexpected keyword argument 'username'

How do I make it so that the min and max length of the username argument is 3 and 22.

Answer

I was able to accomplish this by using app_commands.Range.

async def inv(interaction:discord.Interaction, username:app_commands.Range[str, 3, 22]):
  # code
