Going off of this question, when using Slack, is there a way that I can click the 'play' button and have it play the full song within the Slack client? Currently I am only getting 30s previews. It doesn't seem to register that I am a premium Spotify user. Or even better, if clicking the play button could automatically load it into the desktop Spotify client and play from there?

I've already tried clearing Slack Cache, uninstalling, reinstalling, logging back into Slack on web & desktop. Nothing seems to work. Thanks for any help!
