I’d like to check if the wp_sitemaps_enabled filter is enabled or disabled. I’ve tried the following and it doesn’t work i.e. the condition isn’t met.

if( array_key_exists( 'wp_sitemaps_enabled' , $GLOBALS['wp_filter'] ) ) {
    // do something
}

if( has filter ( 'wp_sitemaps_enabled') ) {
    // do something
}

Is there another way of checking?
