Include custom styles for Gutenberg Block

Hello, I have a trouble with my block styles that doesn’t loaded in the AMP page. I’m talking about this plugin https://wordpress.org/plugins/recipe-card-blocks-by-wpzoom/. Do you have any hooks that can help me to include my block styles? I have tried with wp_enqueue_scripts but without success 😔
There is my code:

function enqueue_styles_for_AMP() {
            $is_amp_endpoint = function_exists('is_amp_endpoint') && is_amp_endpoint();
            $is_ampforwp_endpoint = function_exists('ampforwp_is_amp_endpoint') && ampforwp_is_amp_endpoint();

            if ( $is_amp_endpoint || $is_ampforwp_endpoint ) {

                wp_enqueue_style(
                        'my-block-style-css',
                        $this->asset_source( '', 'blocks.style.build.css' ),
                        $this->get_dependencies( 'my-block-style-css' )
                );

            }
        }

add_action( 'wp_enqueue_scripts', 'enqueue_styles_for_AMP' );
