automatically refresh Sheets chart in Google Slides

I have a chart within google sheets that I would like to have automatically update in google slides every hour. I know you can refresh using the Tools menu and selecting linked objects but I would really like to automate this process without use of a Slides AddOn

• You want to refresh a chart in Google Slides every 1 hour.
• The chart was put from Google Spreadsheet.
• You want to achieve this using Google Apps Script.

If my understanding is correct, how about this answer? Please think of this as just one of several possible answers.

Pattern 1:

In this pattern, all charts in all slides in the Google Slides are refreshed.

Sample script:

function myFunction() {
  var slidesId = "###";  // Please set the Slides ID.

  SlidesApp.openById(slidesId).getSlides()
  .forEach(function(s) {
    s.getSheetsCharts().forEach(function(c) {
      c.refresh();
    });
  });
}

Pattern 2:

In this pattern, all charts in 1st slide in the Google Slides are refreshed.

Sample script:

function myFunction() {
  var slidesId = "###";  // Please set the Slides ID.

  SlidesApp.openById(slidesId).getSlides()[0]
  .getSheetsCharts()
  .forEach(function(c) {
    c.refresh();
  });
}

Note:

• In order to automatically run every 1 hour, please install the time-driven trigger to the function of myFunction(). By this, myFunction() is run every 1 hour.
