You need to some JS here.

Check if page gets reloaded or refreshed in JavaScript - Stack Overflow

Hey!

You can add an event listener in JavaScript.

// Store a flag in session storage

if (sessionStorage.getItem('is_reloaded')) {

    console.log('Page was refreshed');

} else {

    console.log('Page was loaded for the first time');

}

// Set the flag when the page is about to be unloaded

window.addEventListener('beforeunload', function() {

    sessionStorage.setItem('is_reloaded', 'true');

});

Explanation:
The beforeunload event is triggered when the user is about to navigate away from the page, including refreshing the page.
SessionStorage can be used to track whether a page load is the first in the session or a refresh. 

Hi @saravanakumar v ,

You can use window.onbeforeunload to detect a page refresh, whether it's triggered by F5, CTRL+R, or the browser's refresh button. However, this event also fires when the user attempts to leave the page in any way, including closing the tab/window or clicking a link. 

You can add the following JS in the OnReady event:

window.onbeforeunload = function() {    

//Your Custom Logic

}

Hi @saravanakumar v ,
You can use the onbeforeunload JavaScript event to detect when a page is being unloaded. This event triggers when the page is refreshed, the tab/window is closed, or a user navigates away by clicking a link.

To implement this, add the following JavaScript code inside the OnReady event:

window.onbeforeunload = function() {    

    // Your custom logic here

};

This will allow you to execute any necessary actions before loading the page.
