I use brave browser to listen to my tidal music on Linux. If you go to the site, on the right side of the button is a small gray icon, click it and it’ll “install” it as an app on your computer (it behaves more as a separate instance of the web browser, like a bookmark you store on your desktop). I haven’t thought to check if it actually downloads the music filesz though I doubt it does. It works, though I can’t say how well it would work on the L5.
