Arduino Uno WiFi control with Smart Phone

I am new to the platform, assist please or steer me in the right direction.
I wish to build an app to control my Arduino Uno WiFi Rev2 board from my smart phone. I can only find tutorials about Bluetooth connectivity. How do I do it via WiFi ?

A search on the community for arduino wifi turned up these results

Anything here that helps ?

Nope, there seems to be a lot about bluetooth connectivity and ESP32 devices but nothing about Arduino UNO WiFi. have I missed it ?
