Sentry Integration before_send

[Lukas Mat]

Hi

I'm trying to setup sentry using documentation

https://airflow.apache.org/docs/apache-airflow/stable/administration-and-deployment/logging-monitoring/errors.html

I want to configure before_send function I'm setting value in airflow.cfg to sentry_integration.setup.before_send Where sentry_integration is python package in dags folder. 

I'm getting ImportModuleError.

How I can pass before_send so it can be imported by airflow. Do I need to create package (in pypi or artfiact registry) and install it as dependency  or there is better way to do this?
