Where Does Parallels Store Downloaded ISO Files?

Hi all,
I am running Parallels 17 on a MacBook Pro M1 Max running macOS 12.3.1. I created two VMs -- Windows 11 and Ubuntu Linux. At each installation, I selected the option to 'Download Windows' and 'Download Ubuntu'. Everything downloaded and installed fine, without issue. Question is this:

I wanted to delete the iso files that the Parallels app downloaded, but cannot find them anywhere. Do any of you know where the files would be?

Thanks in advance.

 

I'm not sure, but I think they are deleted after installation.
