Sorry, the documentation on the official website has not yet been updated, please try using the following code.

#include <M5Core2.h>

Button lt(0, 0, 160, 120, "left-top");
Button lb(0, 120, 160, 120, "left-bottom");
Button rt(160, 0, 160, 120, "right-top");
Button rb(160, 120, 160, 120, "right-bottom");

  void colorButtons(Event& e) {
    Button& b = *e.button;
    M5.Lcd.fillRect(b.x, b.y, b.w, b.h, b.isPressed() ? WHITE : BLACK);
  }

  void dblTapped(Event& e) {
    Serial.println("--- TOP RIGHT BUTTON WAS DOUBLETAPPED ---");
  }

  void setup() {
    M5.begin();
    M5.Buttons.addHandler(colorButtons,  E_TOUCH + E_RELEASE);
    rt.addHandler(dblTapped, E_DBLTAP);
  }

  void loop() {
    M5.update();
  }
