ADAL JS integration on dynamic crm failed to get power bi rest api, getting 403

[ShahriatHossain]

I have integrated adal.js library in my dynamic crm custom solution. I can get token easily but when trying to call power bi rest api using the following code below getting 403 unauthorized status:

var headers = new Headers();
                    var bearer = "Bearer " + token;
                    headers.append("Authorization", bearer);
                    var options = {
                        method: "GET",
                        headers: headers
                    };
                    var graphEndpoint = "https://api.powerbi.com/v1.0/myorg/reports";

                    fetch(graphEndpoint, options)
                        .then(function (response) {
                            //do something with response
                            console.log(response);
                        });

Do I need to use username and password and how to use it using adal.js, any suggestion?

Thanks in advanced.
