It's much more common to use an ESP8266 to provide wifi for an Uno. The ESP32 is a much more powerful part, more appropriate for use as the main microcontroller for a project. The ESP8266 was originally intended for use as a wifi adapter, and the AT firmware used for that purpose is widely available and often what is loaded onto the modules at the factory. Arduino libraries for using an ESP8266 with AT firmware are widely available and well supported.

If similar AT firmware for ESP32 exists, that could be used - but A) I don't know if anyone's bothered to write it, and B) It costs 5 times as much as an ESP8266 and you're using none of that enhanced capability.
