Since Streamlit has a server-client architecture, all the Python commands and logic are going to run on the machine that hosts the app as opposed to any other machine being used to view the app. So even if you did install Chrome on the host machine, your viewers would not see Chrome open for them as that would all be happening within the container on the Community Cloud servers.
