from airflow import DAG

The with construct really has nothing to do with it, but it is a
common source of confusion:
# incorrect
with DAG("my_dag"):
...
It is less obvious (to some) in this way that the entire DAG will not
be picked up. You will in fact have to write:
# correct
with DAG("my_dag") as dag:
...
This way, you're capturing the DAG in the top-level scope which is the
requirement.
