Once the files have been recorded and saved, this shortcut sends you a link to all the recordings you created on a given day. You can choose to send the email to yourself or someone else.
The shortcut has to work this way because of how iCloud file storage works. The share link can't be known until the file completes uploading, so the links can't be sent out instantaneously when the recordings are generated. And because the files take a really long time to search directly, we have to store them in a text file that takes less time to search.
