Hide CDF navigation for Streamlit Custom App

Hi Cognite Community,

we currently have a Streamlit Custom App hosted directly in Cognite Data Fusion that we would like to provide to end users for an upcoming testing phase.

Our plan is to let the users test the current Streamlit version first, while in parallel we are working on migrating/rebuilding the application as a Flows app.

However, this migration will still take some time, while the users are expected to start testing the Streamlit application in approximately two weeks.

For the testing phase, we would therefore like to provide users with a direct link to the Streamlit application, but ideally without showing the surrounding CDF navigation/sidebar (Home, Search, Canvas, Charts, Custom Apps, etc.).

The goal would be something similar to a standalone/full-screen application experience while still keeping the current Streamlit app hosted and authenticated through CDF.

Is there currently any supported way for Streamlit Custom Apps to:

• hide the CDF shell/sidebar,
• open the application in a standalone or full-screen mode,
• or use a URL parameter/configuration option to access the Streamlit app without the CDF navigation?

We are aware that this can be handled differently with Flows, and Flows is our target solution. We are specifically looking for an interim solution for the upcoming Streamlit testing phase until the Flows version is ready.

Thanks in advance!
