Removing Site Header from Entire Site in Astra Theme

I am globally removing the site header from entire site. I’m not using the Astra Pro version. So I am not sure that this option is available or not. I used following tips which I am sharing at below:

Open your functions.php file of your Astra child theme and drop this simple PHP code there.

/**
 * Removing the site header
 */
function astra_header_markup() {
	return false;
}
