VNC - can Winkey be passed to server?

Hi,

I'm using ASG RD 2019. 
When I connect to a VNC server on a Windows machine and press the Winkey, the operation is performed on the local machine and not on the server. Is there an option to send the Winkey to the VNC server (as in RealVnc "Pass special keys directly to VNC server" option)? 

Regards,
