Custom Python Modules

On our current project, we have shared modules folders with logic to interact with multiple partners apis.
Structure sample:
-root-
– flows
– – partner1
– – – flow1.py
– shared
– partner1_shared.py

How do I reference the partner1_shared module? Its shows as not found on the deploy.

The solution was to develop the shared module as a package that needs to be installed when the agent starts.
When deploying the agent added a step pip to install it directly from git.
