How to call python file in repo in databricks from data factory outside DBFS?

In Azure Databricks I have I have a repo cloned which contains python files, not notebooks. In Azure Data Factory I want to configure a step to run a Databricks Python file. However when I enter the /Repos/..../myfile.py (which works for Databricks Notebooks) it gives me the error " DBFS URI must starts with 'dbfs:'" How can I reference a python file from a report which is not in dbfs? NOTE I see a duplicate question here but the answer was just to wrap it in a Databricks Notebook - OK workaround but when I do it I get "No module named 'my_python_file'" https://stackoverflow.com/questions/70096408/how-to-create-a-databricks-job-using-a-python-file-outside-of-dbfs
