Trying to make a PAD flow that is scheduled to run daily. Have a gateway setup and have the flow setup and running in PAD manually. I setup a scheduled cloud flow and try to add a "Desktop Flow" to it. It has you enter a gateway, domain/user, and password. I keep getting this error no matter what I enter for the "Domain and username" field

The (slightly out of date) documentation for this field online says
Domain and Username: Provide your device account. You can use a local account by using the name of the user (for example, “MACHINENAME\User” or “local\User”), or an Active Directory account such as “DOMAIN\User”.
And I've tried all kinds of combinations of the machine name\user, domain\user, and machine name.domain\user and it can't seem to connect at all.
I don't know if the fact I am logged into one machine and remoting onto another is causing some confusion here? The machine I am remoting into is the one with PAD installed that I am trying to schedule it to run this on. I also don't have admin privileges, so don't know if that would cause this error?
