Track Matcher Creating Spotify/Tidal Playlist From missing tracks

I could have sworn that missing tracks on from Track Matcher were able to be converted to a Spotify Playlist very easily on rekordcloud.
I’m finally giving Lexicon a go and the feature is not there nor on rekordcloud.

If you use a Spotify playlist link as input, then a button will appear when you switch to the “not found” tab on the results page. The button doesn’t appear if your input was not Spotify.
