Hello, @M Arsal,
Thanks for using our Theme.
I have checked your site on page speed insights and found that there are some things that need to be optimized like “Server respond time, CSS, and image” see image: https://postimg.cc/1VcGy4M6 the thing is when you optimized the CSS and images the server response time will affect auto to optimize the CSS and image you can use any third-party plugins, especially WP Rocket plugin once you are done with the optimization check the site speed you will get a better result.
