how to define a favicon?

You should be able to put a favicon.ico into the overlayFSPath specified within your Customization. As the browser asks for that file it should be grabbed and displayed.

# Custom path to override embedded resources. You can override any
# file present in the `frontend` directory (which is baked into the
# binary during compile-time). You also can add new files (for
# example the appIcon given above). Those files are available at the
# root of the application (i.e. an app.png would be served at
# https://ots.example.com/app.png).
overlayFSPath: /path/to/ots-customization

Create a folder, put in the icon
