When I type out something like np. I think this triggers Visual Studio Code + Pylance’s (not sure) auto-import completion by suggesting that import numpy as np might be relevant.

I would like to create similar custom auto-import/complete associations. For example: between pl and polars, so that if I type something like pl. then import polars as pl is given as an auto-import suggestion.

How can I do this? Is this specific to the Pylance extension I am using, or something about Visual Studio Code?
