Power Apps Commanding with Power FX - How to Show/Hide a Button

In this video I go through a brand new feature currently in public preview, Command Designer. The Command Designer allows you to easily use Power Fx to create custom buttons in the command bar. I show how you can show or hide a button in the command bar, using Power Fx. This can be used to extend Model-driven apps even further, using an in-built method to customise the user experience.

Hi Matt, thank you for the video. it looked so easy.
but when i try to go in and e.g. hide buttons it will not allow me to do anything other than creating new buttons? do you know if there has been an update since you made the video?

Hi Sir, I want to hide the button based on logged in user security role. Is it possible using fx functions.
When I try using certain table using Display Name they are not available in formula bar
