Roblox OAuth 2.0 with Auth0

[Leone7_22]

Hello!
I would like to integrate the Roblox OAuth 2.0 Authentication into Auth0.
I already setup it:

And this is my user fetch script:

function(access_token, ctx, callback){
  
  request({
    method: 'GET',
    url: 'https://apis.roblox.com/oauth/v1/userinfo',
    headers: {
      Authorization: 'Bearer ' + access_token
    }
  }, function(err, resp, body) {
      
      if(err) {
        return callback(err);
      }
      
      if(resp.statusCode !== 200) {
        return callback(new Error('StatusCode:' + r.statusCode));
      }
      
      let profile = {
  "sub": "1516563360",
  "name": "exampleuser",
  "nickname": "exampleuser",
  "preferred_username": "exampleuser",
  "created_at": 1584682495,
  "profile": "https://www.roblox.com/users/1516563360/profile",
  "picture": "https://tr.rbxcdn.com/03dc2a9abe7b1aacaaf93ea46d5c0646/150/150/AvatarHeadshot/Png"
      };  
      callback(null, profile);
    });
}

however when I test it there are 2 problems:

1. Roblox says “Account selection prompt is required for this request.” but when I remove the &prompt=login from the url it works. URL https://authorize.roblox.com/?client_id=3035920536971400383&response_type=code&redirect_uri=https%3A%2F%2Fmerutagroup.eu.auth0.com%2Flogin%2Fcallback&scope=openid+profile&state=urOJd-vbPI5ioFJHqZzWxo-6XNca7-tj&prompt=login
2. When everything is done, Auth0 says:
   
   

Please help me with this, thank you so much.
