Add Style to PG Gutenberg Block?

Hi, I’m able to add styles to core blocks but when I try the exact same code for PG blocks I can’t get the styles to show up:

wp.blocks.registerBlockStyle('core/image', {
      name: 'image-border-radius-lg',
    	label: 'Rounded Corner Large'
    }
  );
  wp.blocks.registerBlockStyle('rental-world/gb-section', {
      name: 'image-border-radius',
    	label: 'Rounded Corner'
    }
  );
function jr_enqueue_block_editor_assets() {
  wp_enqueue_script( 'g_blocks', get_template_directory_uri() . '/a_js/g-blocks.js', array( 'wp-hooks', 'wp-blocks', 'wp-dom-ready', 'wp-edit-post' ), null, true );
}
add_action( 'enqueue_block_editor_assets', 'jr_enqueue_block_editor_assets' );

Actually, it’s working (I’m not sure what changed) but I guess I’ll leave this here in case anyone wants to use this as a reference to manually add styles to a block.
