[Question / Feature request] Gutenberg block with repeater field on external page

We have posts with blocks. Some blocks have ACF repeater fields.

however we can't acces those fields on archive page.

we have following code to get the field data:

function get_field_from_block($post, $block_name = 'core/heading', $field_name = "" ){
	$content = "";
	if ( has_blocks( $post->post_content ) && !empty($field_name )) {
	    $blocks = parse_blocks( $post->post_content );
	    foreach($blocks as $block){
		    if ( $block['blockName'] === $block_name ) {
		    	if(isset($block["attrs"]["data"][$field_name])){
                             $content = $block["attrs"]["data"][$field_name];
		    	}
		    }	    	
	    }  
	}
	return $content;
}

however it returns unformated values and as for repeater field it returns number of rows.

How can we get the contents of the rows ?
also how can we format the output as it was stated in backend for that field ?

Start with the supplied get_field_from_block() function and its parse_blocks() call, reproducing the ACF Gutenberg repeater case on an archive page. Determine how repeater row contents and formatted field output should be retrieved, then verify that both are available consistently outside the editor.
