Please include your relevant experience in your application.

I have a firebase project based on CoreUI (https://coreui.io/product/free-bootstrap-admin-template/), and I would like to add Spotify Authentication.

When the user visits the login page (CoreUI example login page is fine) there should be a Spotify button. When the user clicks on the spotify button, a popup for spotify authentication should be shown, and when the user completes successfully, a user document should be added to firebase at users/ as I will want more information about this user later. The site should return the user to my main page, logged in. Then it should pull pull the following from the Spotify user account and save the output into /users/{docid}/spotify:
user-follow-read
user-top-read
user-read-recently-played
user-library-read
user-read-email
(From https://developer.spotify.com/documentation/web-api/concepts/scopes).

I have setup Firebase Authentication using a OpenID Connect for spotify with Provider ID: oidc.spotify.
