No network port

I'm relatively new to Arduino and wanted to use OTA in the development of an autonomous lawnmower. Quite large to bring inside to connect to USB!
I have the board working as a simple Web server, address pings successfully on my network, but there is no network port showing in the "ports" section so I can't proceed with any OTA work.
Can anyone help me with a solution please?
Several days Googling has not got me any further.

I don’t believe the Uno WiFi Rev2 has that capability. However, I think it is available for the ESP8266 module. Please see the ESP8266 OTA Updates with Arduino IDE | Over the Air tutorial. Personally, I do not have any experience in OTA updates, but thought I would pass along that tutorial I found in case it helps you.
