What are the current OAuth URLs and scopes for Microsofts infrastructure?

I am trying to build a bot that will need a basic outlook login. I was watching this video

https://channel9.msdn.com/events/Build/2017/P4063?term=cortana%20skill

and the guy at 17:02 adds the following values for scopes and Authorization and Token URLs:

wl.basic wl.birthday
https://login.live.com/oauth20_authorize.srf
https://login.live.com/oauth20_token.srf

then I stumbled across Microsoft's documentation:

https://docs.microsoft.com/en-us/cortana/tutorials/bot-skills/bot-skill-auth

where it says that the values for the scopes and URLs are:

User.Read offline_access openid
https://login.microsoftonline.com/common/oauth2/v2.0/authorize
https://login.microsoftonline.com/common/oauth2/v2.0/token

The video is from May 10, 2017 (which was the BUILD 2017), and the article is from April 08, 2017. So which one is correct/deprecated? Also I tried to mix them and this is what the Login prompt looks like with the different combinations:

As you can see all four variations of scopes/urls produce totally different sign in UI?!?!?! (and the ones at the right column also look slightly broken) Which is the correct way?

UPDATE Also, following the article I added a singin card to my bot with the URL described in the documentation:

var message = context.MakeMessage() as IMessageActivity;
message.Speak = "This is a Sign-in card";
message.Summary = "This is a Sign-in card";
message.Text = "Message Text";
message.Attachments = new List<Attachment>(){
    new SigninCard("You need to authorize me", new List<CardAction>()
    {
        new CardAction()
        {
            Value = "https://login.microsoftonline.com/?redirect_uri=http%3a%2f%2fbing.com%2fagents%2foauth",
            Type = "signin",
            Title = "Connect"
        }
    }).ToAttachment()
};
await context.PostAsync(message);

and to my surprise clicking the sign in button, an entirely new login UI, resembling Office 365 pops up:
