Remove jetpack share from post excerpts

Hello, I have tried using the code below however it does not work:

// Remove JetPack sharing buttons from post excerpt

add_action( 'init', 'my_remove_filters_func' );

function my_remove_filters_func {
     remove_filter( 'the_excerpt', 'sharing_display', 19 );
}

Does anyone have another solution for this? Thanks.
