Shere screen from client

I have a Workplace pro plan and I use Zoom in a therapy context with only one client at a time. Before the client could share his screen with me just by clicking "share" but now, a window appears and it says "Allow Zoom Workplace to share your screen. Open system settings security and privacy to grant access." I tried going to the computer settings to security and privacy but I don't have any information where it says to allow Zoom workplace. My client doesn't know what to do and neither do I. Can someone help me.
