i´m not able to find any solution that solves my Problem.

I use Firebase and Facebook to sign up to my app.

When I first sign up to my app, i get the following screen:

Facebook First Login-Screen

I sign out from Firebase and Facebook using the following Lines of Code:

FirebaseAuth.getInstance().signOut();
LoginManager.getInstance().logOut();

When I´m trying after that to sign in with Facebook again, I get the following Screen:

Facebook Second Login-Screen

I´m only able to continue with the Account I used before.
I want to come back to the first Screen, where I have to enter E-Mail an Password so I could Sign in with another Facebook Account if I want.

On Stackoverflow I found the following promising Code:

FacebookSdk.sdkInitialize(getApplicationContext());
 if (AccessToken.getCurrentAccessToken() != null) 
 new GraphRequest(AccessToken.getCurrentAccessToken(), "/me/permissions/", null, HttpMethod.DELETE, new GraphRequest.Callback() 
 @Override
 public void onCompleted(GraphResponse graphResponse) 
 AccessToken.setCurrentAccessToken(null);
 LoginManager.getInstance().logOut();
 
 ).executeAsync();
 

But this solved also not my Problem.

After that I get the following Screen:

Facebook alternate Second Login-Screen

I would by very thankful for any help and sorry for any English mistakes.
