Activating bridge_20 wp theme without a key and purchase data (API-Token) on Envato - how to activate without entering a key?

Question

Envato

The theme was purchased here: www.themelock.com/wordpress-themes/687014079-bridg... and there are a number of similar resources where full new themes and plugins are taken for free, for example: https://www.genesisforwp.com/ It makes no sense to spend registration of such products at https://build.envato.com/termsin the API Services Terms and Conditions - they were not purchased there and there is no information about purchases in the service downloads! What then to do - "do not start the car without a key!". When entering the "key" in the registration field, for example, if Chrome is used, you can open a code in which the input field is visible in java-script, and each section of this page and even the place - where you need to enter the key, but I don't know, how it is edited and in general - first came across a similar problem. A few times, in passing, on GitHub, I came across patches for bypassing the key entry, like this:
enenvato / verify -purchase.php

<?php
include('envato-api-class.php');
if(isset($_POST['submit']))
{

// Assign data to variables
$username = $_POST['
$item_id = $_POST['item_id'];
$purchase_code = $_POST['purchase_code'];

// Check if all fields are filled in
if(!empty($username) && !empty($item_id) && !empty($purchase_code))
{
$API = new envatoAPI();
$API->set_api_key('ahdio270410ayap20hkdooxaadht5s');
$API->set_username('JohnDoe');
$API->set_api_set('verify-purchase:' . $purchase_code);

$data = $API->request();

if(!empty($data))
{
// We got a valid API response let's match the item id and the username
if($data['verify-purchase']['item_id'] == $item_id &
{
// Everything seems to be correct! Purchase verified!
// Show some info like purchase date and license
echo 'You have purchased the item on ' . $data['verify-purchase']['created_at'] . ' with the ' . $data['verify-purchase']['licence'] . '!';
}

}
else{
// Response from the API was empty, return error
echo 'Sorry, we are unable to verify your purchase.';
}

}
}
?>



Verify Purchase



Marketplace Username:


Item ID:


Purchase code:





but how to apply them really, without detailed instructions - there is no description ... A hint is needed or a more or less reasonable explanation of the possibility of using the theme without entering an activation key. Thanks in advance for your response to this thread.
