Airflow: Convert one digit to two digit with execution

I am trying to convert my airflow date from one digit to two digit. At the moment when I use {{ execution_date.month }} my month becomes 1 but would like it to become 01.

I have tried with {{ execution_date.month.strftime("%m") }} but get the error:

int object' has no attribute 'strftime

You can do:

from datetime import datetime
from airflow.models import DAG
from airflow.operators.bash import BashOperator

with DAG(
    dag_id="bash_example",
    schedule_interval=None,
    start_date=datetime(2022, 1, 19),
    catchup=False
) as dag4:

    BashOperator(task_id="task", bash_command="echo {{ execution_date.strftime('%m') }}")

from datetime import datetime
from airflow.decorators import dag
from airflow.operators.bash import BashOperator

@dag(schedule_interval=None, start_date=datetime(2022, 1, 19), catchup=False)
def bash_example():
    BashOperator(task_id="task", bash_command="echo {{ execution_date.strftime('%m') }}")


dag = bash_example()
