Is there a way to change all borders of all tables in Google Docs at once?

I'm trying to change all border width of all tables in my document to 0.

Below you'll find the script that I'm using, when I try to run it it doesn't work. Am I missing something?

I've filled in my DOCUMENT_ID but removed it in the snippet below.

function setTableProperties() {
  var doc = DocumentApp.openById("DOCUMENT_ID");
  var tables = doc.getBody().getTables();

  tables.forEach((table) => {
               table.setBorderWidth(0);
  });
}
