Hi!, I have solve the problem with this:

import {UserAgentApplication} from "msal";

const config = {
auth: {
clientId: "client-id",
 authority: "https://login.microsoftonline.com/tenant-id"
 }
};

const myMSALObj = new UserAgentApplication(config);

let accessTokenRequest = {
scopes: ["user.read"],
 loginHint: this.context.pageContext.user.loginName,
 extraQueryParameters: {domain_hint: 'organizations'}
}

myMSALObj.acquireTokenSilent(accessTokenRequest).then(function(accessTokenResponse) {
// Acquire token silent success
 // call API with token
 let accessToken = accessTokenResponse.accessToken;
 let scopes = accessTokenResponse.scopes;
 }).catch(function (error) {
//Acquire token silent failure, and send an interactive request
 console.log(error);
 if (error.errorMessage.indexOf("interaction_required") !== -1) {
myMSALObj.acquireTokenRedirect(accessTokenRequest);
 }
});
