Airflow not picking up dags from a helper class

I tried to experiment with a helper class that can create a dag with the parameters passed in . but when I try to import the class in my dag file, airflow doesn't pick it up.

Here's my helper class:

from airflow.models.dag import ScheduleInterval
from airflow.operators.bash import BashOperator
from datetime import datetime, timedelta, date

class dagClass:
    def __init__(self) -> None:
        self.dag = None

        self.args={
        'owner': 'airflow',
        'depends_on_past': False,
        'start_date': datetime.now()-timedelta(days=1),
        'email': ['airflow@airflow.com'],
        'email_on_failure': False,
        'email_on_retry': False,
        'retries': 1,
        'retry_delay': timedelta(minutes=1),
        }
    def create_dag(self,dagName):
        print(type(self.args))
        self.dag=DAG(dagName, 
        default_args=self.args,
        schedule_interval="39 8 * * *")
        return self.dag
    def get_dag(self, dagName):
        dag = self.create_dag(dagName)
        print(type(dag))
        return dag

    def add_task(self,dag,taskID, scriptPath):
        return BashOperator(
            task_id = taskID,
            bash_command = "python3 {}".format(scriptPath),
            dag = dag
        )

and here's how I am importing it

from dagClass import dagClass

dagObj = dagClass()

dag = dagObj.get_dag("testClass21")

t1 = dagObj.add_task(dag,"t1","test.py")


print(type(dag)) #<class 'airflow.models.dag.DAG'>
print(type(t1)) # <class 'airflow.operators.bash.BashOperator'>

t1

anybody has any idea on what's wrong? airflow is picking up the other dags I created so it isn't a problem with the folder.
