This array only contains one element. This is because, if a multi-page design is exported as multiple files, the files
are exported in a ZIP file. In the future, there'll be an option for each file to be a separate element in the array.
If a user's design contains multiple pages but is exported in a format that doesn't support multiple pages,
this URL will point to a ZIP file that contains each page as a separate file.
For example:
If a single-page design is exported as a JPG, the URL will point to a JPG file.
If a multi-page design is exported as a JPG, the URL will point to a ZIP file that contains a JPG file for each page.
If a multi-page design is exported as a PDF file, the URL will point to a PDF file.
The following file types support multiple pages:

"PDF_STANDARD"
