Varying number of instagram images in carousel post

I am wanting to pull the most recently added row in a sheet and then funnel the links in the cells of the row into the instagram carousel post to make the post. The problem I am running into is that I cant figure out how to have a non fixed number of images in the carousel.

Looks like you need to Iterate over the URLs, download the URLs, then aggregate to array.

Then map that array into the files field
