[In Salesforce Marketing Cloud] Some permissions have outdated names or seem quite vague, but this is probably the only permission where I have absolutely no idea what it is referring to. It doesn't even expand when you hit the + symbol. Anybody have any knowledge of this?
So, I DO know the answer, but I need to be intentionally vague as to not violate confidentiality. It is the permissions for an app of one particular customer. I do not know why you're seeing this. It's not a security issue, because if you don't have the app installed, there is nothing to configure.
Hope this helps. Sorry I cannot be more specific.
