I have coded it, but it doesn't redirect to the received page, my gateway supports one return URL, and as soon as the client pays, it shows a blank page. and the transaction is added. I have tried $this->redirect invalidate, but it doesn't work at all. now help, please. how do I redirect the client back to the client's page? 
	 
	 
 
    $redirectUrl = "https://domain.com/client/payments/success";
            $this->redirect($redirectUrl); // Use Blesta's redirect method
	also checked that, but doesn't work 
 
	 
 
	sucess()
 
 public function success(array $get, array $post)
    {
        $validatedData = $this->validate($post);
       
        if ($validatedData) {
            $redirectUrl = "https://domain.com/client/payments/success";
            $this->redirect($redirectUrl); // Use Blesta's redirect method
            exit;
            return $validatedData; // Return the already validated data
        }
    
        echo "Validation failed."; // Handle failure case
        return null;
