RSPAN on Unifi Switches

Hi all , Looking to see if anyone has implemented RSPAN successfully in a large deployment using Unifi Switches and could pass on any tips?

We replaced our aging Netgear switches with Unifi kit ( 32 switches in total over 6 cabinets)
Issue we have now is our Darktrace Unit isn’t able to see any of our network traffic except the switch its physically plugged into

I know it cant be done using GUI and needs to be done using the CLI
