Wordpress post from appsheet record

I did build an Appsheet. I also have a Wordpress website build with Oxygen. I need to be able to post from the Appsheet live to the wordpress blog. I need to be able to insert an image from Appsheet to become the featured image from the blog. I did create a scenario with Integromat, but cannot figure out how to bring the image into the blog. Help me to do this and I will have other tasks for this website and others.
