What are the type hints in Python models ?

[adrien-turiot-maxa]

In a python models, we would like to have type hints.
But the dbt argument does not have any definition, for example here:

from snowflake.snowpark.session import Session

def model(dbt: ???, session: Session):
    ...

It looks like this is a generated class like main_module.dbtObj 🤔

Is their a type available for this value ?
