Doesn't work on my desktop (ubuntu). Browser (brave) pops up a modal window saying the app needs to be installed but there is no way to do it.

ahh. Thank you for the tip. It looks like it installed with no notification (that I can remember). I can run it from Ubuntu apps. The problem with the modal window remains though. That's confusing.
