Setting the data only once in the database.

Assume I have the following setup :

//This example shows how to read, store and update database using get, set, push and update functions.
//Required HTTPClientESP32Ex library to be installed  https://github.com/mobizt/HTTPClientESP32Ex

#include <WiFi.h>
#include "FirebaseESP32.h"

#define FIREBASE_HOST "YOUR_FIREBASE_PROJECT.firebaseio.com" //Do not include https:// in FIREBASE_HOST
#define FIREBASE_AUTH "YOUR_FIREBASE_DATABASE_SECRET"
#define WIFI_SSID "YOUR_WIFI_AP"
#define WIFI_PASSWORD "YOUR_WIFI_PASSWORD"

//Define Firebase Data object
FirebaseData firebaseData;

void setup()
{

  Serial.begin(115200);
  Serial.println();
  Serial.println();

  WiFi.begin(WIFI_SSID, WIFI_PASSWORD);
  Serial.print("Connecting to Wi-Fi");
  while (WiFi.status() != WL_CONNECTED)
  {
    Serial.print(".");
    delay(300);
  }
  Serial.println();
  Serial.print("Connected with IP: ");
  Serial.println(WiFi.localIP());
  Serial.println();

  Firebase.begin(FIREBASE_HOST, FIREBASE_AUTH);
  Firebase.reconnectWiFi(true);

  //Quit Firebase and release all resources
  Firebase.end(firebaseData);
}

void loop()
{
  if (Firebase.pushInt(firebaseData, "/test/append", 0)) {
    Serial.println("Success");
  } else {
    Serial.println(firebaseData.errorReason());
  }
}

I am also running a MQTT server on the same ESP32 device and hence the MQTT has to publish a message on the push of a button. Is it possible for me to add the data to the database only once for every push of a button rather than continuously populate the database ?
