Inserting images into slides from a URL in sheets

Question

I am setting up a deck to automatically create a new slide with each row in a spreadsheet.

Each row has a different picture attached to it, which has the URL in a column on the source spreadsheet, and I would like this image to be inserted into the slide, alongside some text.

The code I am using to populate the text fields is below - this works fine:

// Insert a new slide by duplicating the master slide.
let slide = masterSlide.duplicate();

// Populate data in the slide that was created
slide.replaceAllText("{{ItemName}}", column[0]);
slide.replaceAllText("{{SKU}}", column[1]);
slide.replaceAllText("{{Price}}", column[2]);
slide.replaceAllText("{{Count}}", column[3]);
slide.replaceAllText("{{Composition}}", column[4]);
slide.replaceAllText("{{Analytics}}", column[5]);
slide.replaceAllText("{{Description}}", column[6]);
**slide.insertImage(???);**

I would like to be able to add the image URL as a new column to the sheet and have the script pull this in and convert it into an image on the slide
