How to implement the screenshot of the application?

Description
The zoom application I downloaded from your official website, when I share the screen, I see that zoom will list the running applications and screenshot of this application. I want to ask you how to implement the screenshot ? I have tried [printWindow] and QT’s [grabWindow] and got some black screenshots

Thanks!
