Get user email into an embedded link

How do I get the user email into the embedded link? I have build a Data Studio report that has a filter on the email when they submit the form.

I followed these instructions: https://radical-analytics.com/smart-data-studio-embedding-b36c6fc9a8ac

var url = ‘Looker Studio Overview [reportid] /page/ [pageid] ?config=%7B%22 [controlid] %22:%22 [condition] %25EE%2580%25800%25EE%2580%2580IN%25EE%2580%2580’ + memberId+ ’ %22%7D’;
document.querySelector(‘#dsFrame’).setAttribute(‘src’, url);

Where it says memberID in the above link, I would like to insert the user.email of the member signed in. Is this possible?
