Importing accessory pages linked to dropdown menu in sidebar

Hi -

I get a build error on the streamlit platform, it can’t find vis_helpers (my folder with accessory pages that are linked to the dropdown menu options). The import vis_helpers statement is in my streamlit_app.py header.

Much like the streamlit app that I am attempting to emulate, my accessory pages are in the right folder, and I have the right import statements in my streamlit_app.py. Below is my development code for streamlit_app.py, my current github does not have the code from below, but does have the accessory pages.

I need help so that I can get my streamlit app to recognize my accessory pages.

I am trying to emulate this app and adapt its github pages:
https://share.streamlit.io/czubert/sersitivis/vis.py

This is my streamlit app:
https://share.streamlit.io/retrosynthesisai/explore_app/main#visualization

This is my github repo:

Here is the development code from my streamlit_app:
