FYI: Here's my working angular 7 solution (simplified for the sake of readability):

import { MsalService, BroadcastService } from '@azure/msal-angular';
import { Client } from '@microsoft/microsoft-graph-client';

private subscription: Subscription;
private graphClient: Client;
private memberRoles: any[];

constructor(
  readonly auth: MsalService,
  readonly broadcast: BroadcastService
) {
  // Initialize Microsoft Graph client
  this.graphClient = Client.init({
    authProvider: async (done) => {
      let token = await this.auth.acquireTokenSilent(["User.Read", "Directory.Read.All"])
        .catch((reason) => {
          done(reason, null);
        });

      if (token) {
        done(null, token);
      } else {
        done("Could not get an access token", null);
      }
    }
  });

  this.subscription = broadcast.subscribe("msal:loginSuccess",
    () => {
      //Get associated member roles
      this.graphClient.api('/me/memberOf').get()
        .then((response) => {
          this.memberRoles = response.value;
        }, (error) => {
          console.log('getMemberRoles() - error');
      });
  });
}
