Importing M3U playlist with Qobuz and Tidal tracks

I have been given M3U playlists that include Tidal and Qobuz tracks; the playlists work in Audirvana. Can such a playlist be imported into Roon?

I copied them to the local Nucleus storage where the music is, but they don’t show up in Roon. Did I do something wrong in trying to import them, or are the files invalid? I have enabled playlist import for the storage location, and for a NAS just in case.

(I don’t know playlists, never use them.)
