I have the same question. I was checking everywhere how to fix one of my USB C ports not working and came accross that. (I already fixed the port).
In my case, it says "read and write and no access" for admin user and everyone, respectively.
I checked on the system report it shows like this:
group.is.workflow.my:
Obtained from: Unknown
Last Modified: 6/1/23, 5:05 PM
Kind: Other
Location: /Users/user/Library/Application Scripts/group.is.workflow.my.app
So I checked on that folder and the icon does not feel right, either.
