Interrupts are unknown for this board, please add to this code

Hi I am using the new Arduino Giga R1 Wifi Board as per data sheet all digital pins are interrupt like Arduino Due. when tested the sample program there is no issue when using other Arduino Boards( Uno, Mega).but when I used Arduino Giga R1 the compilation error shows in Arduino IDE. please check the issue and fix.

Hardware & Software

Board: ARDUINO GIGA R1 WIFI
Shields / modules used
Arduino IDE version: 2.1.0
Teensyduino version (if using Teensy): NO
Version info & package name (from Tools > Boards > Board Manager)
Operating system & version: windows 10
Any other software or hardware?
NO

Arduino Sketch

#include <Encoder.h>
Encoder myEnc(46, 47);

void setup() {
Serial.begin(9600);
Serial.println("Basic Encoder Test:");
}

long oldPosition = -999;

void loop() {
long newPosition = myEnc.read();
if (newPosition != oldPosition) {
oldPosition = newPosition;
Serial.println(newPosition);
}
}

I'm still seeing this error on the Giga. I've checked the verbose output of compilation and it's using -DARDUINO_GIGA

Note that I'm erroring out a message to show that ARDUINO_GIGA truly is defined.
