yt-dlp, Shortcuts, hidden files and directory paths

Hello,
I recently tried using an iOS Shortcut to automate the yt-dlp process. However, for some reason anytime the shortcut runs, I am unable to find the downloaded file on my device. A search of the iOS Files App returns nothing, but I know it's there because if I try to download the same file again (manually entering the command this time), I get the message that the file already exists.

I've noticed that, although the terminal launches with [Documents]$ as the default directory, after I run the shortcut the terminal shows [~group]$ as the current directory.

I did think to explicitly set the file's download path with a yt-dlp command, but I haven't been able to determine what the full path is to the default "On My Phone -> a-Shell" directory. Can you advise that also?

Thanks for creating and supporting such a fantastic app, btw!
