How can I hide the progressbar for PlayerView?

I noticed that I can't access the progress bar through the player view. I need to use my own progress bar. Thank you

Start by locating the sample app's PlayerView usage and reviewing how the Android IVS Player SDK exposes the progress bar. Confirm whether the built-in progress bar can be hidden so a custom progress bar can be used, and make the supported approach clear in the sample or its documentation.
