How to Get the RSSI value for Multiple devices while scan by ESP32 - arduino-esp32

Question

I am using the below code to get the RSSI value. I am able to get the value successfully for one Device at a time. But I am confused about how to get the RSSI value for multiple devices while scanning by ESP32.
The below code snippet I am using.
#include <BLEDevice.h>
#include <BLEUtils.h>
#include <BLEScan.h>
#include <BLEAdvertisedDevice.h>
int scanTime = 10; //In seconds
BLEScan* pBLEScan;
class MyAdvertisedDeviceCallbacks: public BLEAdvertisedDeviceCallbacks {
void onResult(BLEAdvertisedDevice advertisedDevice) {
Serial.printf("Advertised Device: %s \n", advertisedDevice.toString().c_str());
Serial.print(" RSSI: ");
Serial.println(advertisedDevice.getRSSI());
}
};
void setup() {
Serial.begin(115200);
Serial.println("Scanning...");
BLEDevice::init("");
pBLEScan = BLEDevice::getScan(); //create new scan
pBLEScan->setAdvertisedDeviceCallbacks(new MyAdvertisedDeviceCallbacks());
pBLEScan->setActiveScan(true); //active scan uses more power, but get results faster
pBLEScan->setInterval(100);
pBLEScan->setWindow(99); // less or equal setInterval value
}
void loop() {
// put your main code here, to run repeatedly:
BLEScanResults foundDevices = pBLEScan->start(scanTime, true);
Serial.print("Devices found: ");
Serial.println(foundDevices.getCount());
// you can access first device with foundDevices.getDevice(0).getAddress()
Serial.println("Scan done!");
pBLEScan->clearResults(); // delete results fromBLEScan buffer to release memory
delay(2000);
}
Can anyone advice how Do I get the multiple RSSI value while scanning devices
