Describe Your Goal
Enumerate parameters returned to the webserver from a submitted page

What Does Your Project Look Like
ESP32 library version 1.0.4
Hessel ESP_HTTPS_Server library version 0.3.1

Hessel HTTPS_Server downloaded via Manage Libraries in the Arduino IDE.

If you can boil your question down to a minimal working example, please do so and share the code here:

void showArgs(HTTPRequest * req) {
  ResourceParameters * params = req->getParams();
 
  for(auto idx = params->beginQueryParameters(); idx != params->endQueryParameters(); ++idx) {
    Serial.print((*idx).first + ":\t");
    Serial.println((*idx).second);
  }

// Original ESP8266 code:
//  for (uint8_t i = 0; i < acnt; i++) {
//    AsyncWebParameter* p = request->getParam(i);
//    Serial.print(p->name() + ":\t");
//    Serial.println(p->value());
//  }
}

ESP32 Module
Please provide specifications of your module

ESP32 - NodeMCU-32S with ESP-WROOM-32

Software (please complete the following information if applicable)

Arduino IDE version 1.8.12
Linux Mint 19.2

Additional context
On the ESP8266 I had a fairly simple routine to show all the submitted parameters for diagnostic purposes. I am trying to write the equivalent routine for the ESP32 and following the example here:

https://github.com/fhessel/esp32_https_server/blob/master/examples/Parameters/Parameters.ino

See lines 282 to 293. However, it seems that beginQueryParameters() and probably endQueryParameters() is not available ? Having had a look at the "documentation" I could not find such a class member in the header file ?
