Starling App Screen Capture

We are planning to demonstrate the 2FA and Approve Anywhere features of Starling mobile application in tandem with SPP.

I want to screen share the Starling mobile application but I noticed that there is no "Screen Capture" option in Starling. Every time I try to share the screen, it just shows a black screen. I was checking other authenticator applications like Microsoft or IBM, and there is an option for "Screen Capture" that allows for the screen to be shared.

I just wanted to check if there is a way to share the screen. Or is there a recommended way of demonstrating the Starling mobile app. Thanks.
