Recognising a new WiFi card in HAOS

I recently installed an Intel 8265NGW Wifi and Bluetooth M.2 card into my Dell Optiplex 3050 MFF (Intel i3-7100T) on which I run the Home Assistant Operating System.

When I restarted HA, the Bluetooth component was immediately recognised but not the WiFi component. Is there some manual step I need to take to stimulate recognition and configuration of WiFi?

I am an HA newbie and the HA WiFi documentation is not all that clear to me, so answer in plain English please!
