IMPORTANT: The AssetService requires you to reuse what you've uploaded previously. Therefore, you cannot create an image asset with the exactly same bytes. In case you want to run this example more than once, note down the created assets' resource names and specify them as command-line arguments for marketing and square marketing images.
Alternatively, you can modify the image URLs' constants directly to use other images.
