Had been waiting for my pi 5 argon case which got lost in the post before I could set this up. Ive been tinkering with an old SFF PC running arch over the last few months to get a "smart tv" set up going that im happy with, now ive condensed it down into a little debian box that uses a fraction of the electricity. Happy days.
Chromium web app. Just go to dotcom/home, and there is an "install" button on the right side of the url bar. Use the home page to skip the main page that says click to enter. The bonus is that you get the benefits of web extensions like ublock and privacy badger.
