Firebase auth Redirect to Facebook app instead of website for login on mobile - firebase-authentication

Is it possible configure my firebase project so that if a user is on mobile and they need to log in, they are redirected to the facebook mobile app instead of the facebook website in their browser?. I thought iOS would automatically intercept the link but it just takes you to the facebook site. Users with the app installed might not already be logged in through their browser since they are used to using the app and i'd like to avoid the extra login step for them

Authenticate web app via Spotify app instead of browser

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.

Facebook Login for Web

According to this link Facebook Login for the Web, I can let my users login with facebook accounts (after logging to my facebook app).
now, all the work is done here in javascript which is a client-based code, it means it is insecure and a hacker could easily trespass my login step.
I know i should be using PHP SDK (for example) to secure the login process, but my question is why would I use this method ????

Did you configure your project's URL Schemes correctly in your info plist?
https://developers.facebook.com/docs/ios/getting-started#configure
The login calls a custom URL that your app has to handle after the authentication is done

How to enable iOS browser to login with facebook from web page (not app)?

I have a web site, that uses facebook to login.
I would like iOS user of safari, to be able to login into this site. You understand i'm NOT talking about a native iOS app..... just a web site visit.
Currently, user can't login from iOS safari, as they can from any desktop environement.
Either login link is inactive, or there is an error message instead of the login popup.
So what should I implement on website to have facebook login work on iOS browser ?
