GenerateToken in Javascript Problem

I'm using this code to login in AAD

function login(network){
	// By defining response type to code, the OAuth flow that will return a refresh token to be used to refresh the access token
	// However this will require the oauth_proxy server
	//Foi feita uma modificação dentro de login ou hello (procurar /organizations) para enviar o <<<<-------------------------<<<<
	hello(network).login({display: 'popup'}, log).then(function(response) {
	log('You are signed in to AAD');
	_sessionData = response;
	// Change button to Sign Out 
	var authButton = document.getElementById('auth');
	authButton.innerHTML = 'logout';
	authButton.setAttribute('onclick', 'logout("aad");');		
	}, function(e) {
		alert('Signin error: ' + e.error.message);
	});
}

function logout(network){
	// Removes all sessions, need to call AAD endpoint to do full logout
	hello(network).logout({force: true}, log).then(function() {
		log('You have Signed Out of  AAD');
		// Change button to Sign in
		var authButton = document.getElementById('auth');
		authButton.innerHTML = "Login AAD";
		authButton.setAttribute('onclick', 'login("aad");');
}, function(e) {
	alert('Sign out error: ' + e.error.message);
});
}

hello.init({
	aad : '16969bc9-xxxx-7290'
},{
	redirect_uri: 'http://localhost/AADeDB/redirect.html',
	resuorce: 'https://analysis.windows.net/powerbi.api',
	scope: 'user.read'	
});

function log(s){
	document.body.querySelector('.response').appendChild(document.createTextNode("\n\n" + JSON.stringify(s, true, 2)));
}

It return: 

{
  "network": "aad",
  "authResponse": {
    "access_token": "eyJ0eXAiOiJKV1QiLCJub25jZSI6...",
    "token_type": "Bearer",
    "expires_in": 3599,
    "scope": "user.read",
    "state": "",
    "session_state": "1b3cb0a4-8d36-4dd6-93ce-121e9e38e13f",
    "client_id": "16969bc9-xxx-ee7290",
    "network": "aad",
    "display": "popup",
    "redirect_uri": "http://localhost/AADeDB/redirect.html",
    "expires": 1517424596.387
  }
}

"You are signed in to AAD"

But using this access token atatching at the header of the message: 

	var request = new XMLHttpRequest();

	request.open('GET', 'https://api.powerbi.com/v1.0/myorg/dashboards');
	var s = 'Bearer '+_sessionData.authResponse.access_token;
		
	request.setRequestHeader('Authorization', 'Bearer '+s);
		
	request.onreadystatechange = function () {
	  if (this.readyState === 4) {
	    console.log('Status:', this.status);
	    console.log('Headers:', this.getAllResponseHeaders());
	    console.log('Body:', this.responseText);
	  }
	};

	request.send();

I got this at the console: 

GET https://api.powerbi.com/v1.0/myorg/dashboards 403 (Forbidden)
Status: 403
Headers: 
Body: 

Any Idea of what can I do?

Im using the libs: hello.js  aad.js  jquery.js and powerbi.js.

I need to get the configurations (embedToken) to set the embedUrl and show the dashboard.

Thx
