Question about custom event handling

[jrobbins-LiveData]

The Mangum doc shows this example of how one might handle a custom event:

def handler(event, context):
    if event.get("some-key"):
        # Do something or return, etc.
        return

    asgi_handler = Mangum(app)
    response = asgi_handler(event, context) # Call the instance with the event arguments

    return response

I need to handle an incoming AWS EventBridge event. I want to invoke the same method that my HTTP API handler is also invoking -- and it is an async method.

Here's what I am using

def handler(event: LambdaEvent, context: LambdaContext) -> dict:
    if "requestContext" in event:
        logger.debug("HTTP API")
        response = fastapi_handler(event, context)
    else:
        logger.debug("Not HTTP API")
        loop = asyncio.get_event_loop()
        response = loop.run_until_complete(app_logic())
    return response

My question(s): Is this the correct pattern to use? In the Mangum source, I see code like this, so I am trying to fit in. My code seems to work, but I read in the Python docs that get_event_loop() is

Deprecated since version 3.10: Deprecation warning is emitted if there is no running event loop. In future Python releases, this function will be an alias of get_running_loop().

Which made me wonder if I were doing this correctly?
