I’m developing a Zoom App to scan QR codes and I want to create a crosshair for the QR code scanning, preferably choosing the target user to set the virtual foreground on. Is this possible? ---

When calling that setVirtualForeground() function as a specific user that will cause the foreground to be applied. More information can be found here: > **[ZoomSdk | @zoom/appssdk - v0.16.22](https://appssdk.zoom.us/classes/ZoomSdk.ZoomSdk.html#setVirtualForeground)** > > Documentation for @zoom/appssdk - v0.16.22 You should be able to call that as the target user to set your overlay. Let me know if that helps!
