How to make email notifications for errors and exceptions?

How to make email notifications for errors and exceptions without changing the file /system/Debug/Exceptions.php?
I want to change error handling without changing engine code!

Isn't this possible in `App\Config\Exceptions` or are you looking for a different solution?

You can't now.
You need to replace Exceptions.

That is, without files in the system folder, is this impossible?

I monitor /writable/logs folder for files every 15 min. If there is error file - script send me motification via telegram or email.

I try it, but this is not work. What is wrong?

PHP Code:

<?php
namespace App\Libraries;

use CodeIgniter\API\ResponseTrait;
use CodeIgniter\Exceptions\PageNotFoundException;
use CodeIgniter\HTTP\CLIRequest;
use CodeIgniter\HTTP\Exceptions\HTTPException;
use CodeIgniter\HTTP\IncomingRequest;
use CodeIgniter\HTTP\Response;
use Config\Exceptions as ExceptionsConfig;
use Config\Paths;
use ErrorException;
use Psr\Log\LogLevel;
use Throwable;

/**
* Exceptions manager
*/
class Exceptions extends Exceptions
{
    /**
    * Gathers the variables that will be made available to the view.
    */
    protected function collectVars(Throwable $exception, int $statusCode): array
    {
        $trace = $exception->getTrace();

        if ($this->config->sensitiveDataInTrace !== []) {
            $this->maskSensitiveData($trace, $this->config->sensitiveDataInTrace);
        }

        $return = [
            'title'  => get_class($exception),
            'type'    => get_class($exception),
            'code'    => $statusCode,
            'message' => $exception->getMessage(),
            'file'    => $exception->getFile(),
            'line'    => $exception->getLine(),
            'trace'  => $trace,
        ];
        
        //send email
        mail('[email protected]', 'test');

        return $return;
    } 


I think "class Exceptions extends Exceptions" does not work.
It seems fatal error.

And the collectVars() method works only in development mode.

yes I use now development mode.
how to fix it to work?

Exceptions::exceptionHandler() is the exception handler.
Override the method.
