I have a web app that is for Spotify users. To authenticate Spotify it currently takes the user to https://spotify.com/en/login?... as described in the Spotify docs. It works fine but it opens Safari instead of the Spotify app. This is an issue because a user may not know their password and then abandon the onboarding flow.
Since the user will be on their phone when accessing the web app, I would prefer to open the Spotify app in order for the user to grant us access. Songkick is able to do it but they do it from an iOS app so I'm not sure if it's possible to do from a web app on mobile to Spotify iOS app.
Also, I am building on Bubble.io which is a no-code builder. I am able to open the Spotify app directly from my web app by using https://open.spotify.com/artist/{artist_id} but that does not seem to work for authenticating.
