It’s been some years since I left the public service, PowerAutomate didn’t really exist back then. It may be an exception to what I said, I do know my current organisation had a few of those Apps running. I wasn’t much involved in the process, but they were basically discovered because of their cost and later shut down. Since I know basically nothing about this process, the PowerApps would have been made by non-developers since I know all the developers in house. I’ll assume they also must have worked.
