redirect after Successfull submit rating?

Hi Thanks for this Plugin It really helpful for my basic need. I not Hardcode Developer and my learning and understanding i create website. now in this website

I would like to redirect user after submit rating. as I see there’s action hook “mrp_after_save_rating_entry_success” but might be it only for pro version i don’t know
Form that I guessing this code

// Redirect to thank after rating
add_action( 'mr_after_save_rating_entry_success' , 'your_redirect_function' );
function your_redirect_function () {
    // Here all you need to do is return the url of your target page.
    $page = '/catagory-+/';
    return $page;
}

Please Correct me if i doing any mistake or guide me if any other way to redirect user after submit rating.
