Sketch Compiles on 1.8.12 IDE But Not 2.0.4

Official Hardware Nano Family Nano 33 BLE

This sketch compiles on the 1.8.12 IDE, but not the 2.0.4.

Compilation error: ArduinoBLE.h: No such file or directory

I was able to specify the Nano BLE 33 board on both IDE's. Why won't the sketch compile on the 2.0.4 IDE? Thanks.

#include <ArduinoBLE.h> 

enum {
  DIRECTION_NONE  = 0, 
  DIRECTION_LEFT  = 1,
  DIRECTION_RIGHT = 2
};
const char* deviceServiceUuid = "xxxx0000-e8f2-537e-4f6c-d104768a1214";
const char* deviceServiceCharacteristicUuid = "xxxx0001-e8f2-537e-4f6c-d104768a1214";
 
int roverDirection=0; 
BLEService directionService(deviceServiceUuid); 
BLEByteCharacteristic directionCharacteristic(deviceServiceCharacteristicUuid, BLERead | BLEWrite);

void setup() {
  Serial.begin(115200);
  while (!Serial);   
  
  if (!BLE.begin()) {
    Serial.println("- Starting Bluetooth® Low Energy module failed!");
    while (1);
  }

  BLE.setLocalName("Arduino Nano 33 BLE (Peripheral)");
  BLE.setAdvertisedService(directionService);
  directionService.addCharacteristic(directionCharacteristic);
  BLE.addService(directionService);
  directionCharacteristic.writeValue(0);
  BLE.advertise();

  Serial.println("Nano 33 BLE (Peripheral Device)");
  Serial.println(" ");
}

void loop() {
  BLEDevice central = BLE.central();
  Serial.println("- Discovering central device...");
  delay(500);

  if (central) {
    Serial.println("* Connected to central device!");
    Serial.print("* Device MAC address: ");
    Serial.println(central.address());
    Serial.println(" ");

    while (central.connected()) {
      if (directionCharacteristic.written()) {
         roverDirection = directionCharacteristic.value();
         writeDirection(roverDirection);
       }
    }
    
    Serial.println("* Disconnected to central device!");
  }
}

void writeDirection(int roverDirection) {
  Serial.println("- Characteristic <direction_type> has changed!");
  
   switch (roverDirection) { 
      case DIRECTION_LEFT:
        Serial.println("* Actual value: LEFT ");
//      do something
        break;
      case DIRECTION_RIGHT:
        Serial.println("* Actual value: RIGHT ");
        Serial.println(" ");
//      do something 
        break; 
      default:
         Serial.println("* Actual value: DEFAULT ");
//      do something
        break;
    }      
}

Theres a new version of mbed. Did you install that?
Its compiling just fine here with the new mbed version.
