What to put to for allowed block list to be able to see this plugin

I have a filter set up for allowed_block_types. In order to use this which folder do I need to allow to see it amongst the blocks?

add_filter( 'allowed_block_types', 'blocks_allowed_block_types', 10, 2 );
		function blocks_allowed_block_types( $allowed_blocks, $post ) {
			if ( $post->post_type == 'post' ) {
				return array(
					'core/shortcode',
					'core/freeform',
					'core/paragraph',
					'core/image',
					'core/buttons',
					'core/heading',
					'core/gallery',
					'core/list',
					'core/quote',
					'core/cover',
					'core/file',
					'core/audio',
					'core/video',
					'core/code',
					'core/table',
					'core/pullquote',
					'core/columns',
					'core/separator',
					'core/spacer',
					'core/media-text',
					'core/embed',
					'core-embed/twitter',
					'core-embed/youtube',
					'core-embed/facebook',
					'core-embed/instagram',
					'core-embed/WPRM',
					
				);
			}
