I cannot find a search function on YouTube Music using Roku. After launching the YouTube app, there is a search icon in the left column, but that is for regular YouTube. Going down that same column, there is a selection for Music. That launches YouTube Music. But, I cannot find a search function from within that. When I use the YouTube Music app on Android, there is a magnifying glass icon for search at the top right. Again, I cannot find such a thing within YouTube Music on Roku.
