send more than one file in the same notification

Summary:

Hello Community,
I have the following problem:
Inside OIC, I have a loop that dynamically loops twice based on the result I get from the database. Each time it loops, it generates a zip file.
When I exit the loop, I theoretically have two zip files generated, each in a different output path.
After the loop ends, I need to be able to attach these two files to the same notification.
I've tried, but it seems the notification only recognizes the file when I put it inside the loop; when I put it outside the loop, it doesn't recognize it.
