[Python] How to use Background Tasks inside a function that is called by a FastAPI endpoint?

I have the below FastAPI endpoint:

@app.post("/abcd", response_model=abcdResponseModel)
async def getServerDetails(IncomingData: serverModel) -> abcdResponseModel:
"""
Get Server Details
"""
result = ServerDetails(IncomingData.dict())
return result


The above is calling the function below

def ServerDetails(IncomingData: dict) -> Tuple[list, int]:
background_tasks = BackgroundTasks()
background_tasks.add(notification_func, arg1, arg2)
response = some operation.....
return response, 500


Is this the way to do this, or do I need to create a BackgroundTasks() object inside getServerDetails endpoitn and pass it to the ServerDetails function?
