Using Google appscript to refresh tables pasted in from Google sheets into Google slides

Question

This question here has as succinct solution for updating Google Sheets charts linked to Google slides.

function onOpen() {
  var ui = SlidesApp.getUi();
  ui.createMenu('Custom Menu')
  .addItem('Batch Update Charts', 'batchUpdate')
  .addToUi();
}

function batchUpdate(){

  var gotSlides = SlidesApp.getActivePresentation().getSlides();

  for (var i = 0; i < gotSlides.length; i++) {
    var slide = gotSlides[i];
    var sheetsCharts = slide.getSheetsCharts();
    for (var k = 0; k < sheetsCharts.length; k++) {
      var shChart = sheetsCharts[k];
      shChart.refresh();
    }
  }
}

I wish to do the same thing but with a table pasted into Google Slides from Google Sheets. I can't see how this would look in the AppScript API for Google Slides. Can someone point out a way forward?

Latest update: There is now an option in Slides's Tools drop-down menu to see all Linked Objects; the menu that appears has the option at the bottom to "Update all".
