%focuskw% Insert Inside Post

Hello, sorry for my English.

Please is it possible to automatically insert focus-keyword in post content using rankmath shortcode “%focuskw%”?

Example below is for yoast seo plugin.

If you want a shortcode for Yoast to output the keyphrase automatically:

function wpso_61018203_output_yoast_keyphrase() {
    // Make sure Yoast is installed/active.
    if ( class_exists( 'WPSEO_Meta' ) ) :
        // Hold the global post object.    
        global $post;

        return WPSEO_Meta::get_value( 'focuskw', $post->ID );
    endif;
}

add_shortcode('yoast_kw', 'wpso_61018203_output_yoast_keyphrase' );

You can then do this [‘yoast_kw’] in your content, or use echo do_shortcode(‘[yoast_kw]’); in your template.
