There's some example code on the github here:

Hi BitBoy01.
With this code, I was able to print the keyboard data on the LCD:

#include 
#include 

#define CARDKB_ADDR 0x5F

void setup()
{
  M5.begin();
  Wire.begin();

  // Lcd display init
  M5.Lcd.setBrightness(10);
  M5.Lcd.fillScreen(BLACK);
  M5.Lcd.setCursor(0, 0);
  M5.Lcd.setTextColor(WHITE);
  M5.Lcd.setTextSize(2);
  M5.Lcd.println("Grove Keyboard");
  M5.Lcd.println("Version 0.1 10.09.2019");

  M5.Lcd.printf("\n");
  M5.Lcd.printf("IIC Address: 0x5F\n");
  M5.Lcd.printf("\n");
}
void loop()
{
  Wire.requestFrom(CARDKB_ADDR, 1);
  while (Wire.available())
  {
    char c = Wire.read(); // receive a byte as character
    if (c != 0)
    {
      if (c == 13)
        M5.Lcd.printf("\n"); // 13 is the new line code
      else
        M5.Lcd.printf("%c", c); // print as character
    }
  }
}

Hope that helps...
