Expected Behavior vs Actual Behavior

I expect Spotdl to add to download queue the playlist songs.

Steps to reproduce - Ensure to include actual links!

1. Start Spotdl web service: /nix/store/44rn0p64x92bnnh7cwn6x6ybvflybmvz-python3-3.13.12/bin/python3.13 /nix/store/j8fwm7wqcr7mv45pccwd111svy42c299-spotdl-4.5.0/bin/.spotdl-wrapped web --config
2. Search a playlist, for example the one from documentation https://open.spotify.com/playlist/37i9dQZF1E8UXBoz02kGID
3. Result: No downloads are queued. Search for a song to begin.
