As of June 2020, can you do it like this. Documentation : https://developers.google.com/identity/sign-in/web/reference

function renderButton() {
      gapi.signin2.render('my-signin2', {
        'scope': 'profile email',
        'width': 240,
        'height': 50,
        'longtitle': true,
        'theme': 'dark',
        'ux_mode': 'redirect',
        'redirect_uri': 'REDIRECT URL HERE',
        'onsuccess': onSuccess,
        'onfailure': onFailure
      });
    }
