Airplay between iPad and Macbook not working

I have an iPad air 2 running macOS 13.6.1 and a Macbook air running Catalina 10.15.6 but I cannot use the side car feature as I am not getting the option for airplay. Is this my devices not being current enough or is there a different problem. I have checked my firewall and it is allowing incoming connections, both the devices are connected to the same network, I have show mirroring options ticked, I have tried restarting both of them, have tried having no other bluetooth devices connected and none of this has worked.

Hope someone can help, thanks :)
