rsconnect::showUsers path not working

I know this is going to be a really simple question but I have tried ever variation I can think of and I can't get rsconnect to work with anything but rsconnect:deployApp. An example below is trying to show users of an App.

rsconnect::showUsers(appDir = getwd("~/Deployed Apps"), appName = "SGBApp")

"Error: No application named 'SGBApp' is currently deployed"

App definitely called SGBApp and is definitely deployed. I've only one account and server linked to RStudio but I've tried including those as well.
