Scripts and styles not added when content called dynamicly

Hello,

I’m using Otter Blocks with Neve theme.

Your integration of Lottie animation is very neat! Thank you for that!

I have an issue that when I call the content of a post in the front page it’s not loading the lottie script (nor the custom css of the content’s section and its content).

I’ve several variation of the same code:

$content_post = get_post($post_id);
$content = $content_post->post_content;
$content = apply_filters('the_content', $content);
$content = str_replace(']]>', ']]>', $content);
echo $content;

and
echo get_post_field('post_content', $post_id);
and

$content = apply_filters('the_content', get_post_field('post_content', $post_id));
echo $content;

and

$post_content = get_post($post_id);
$content = $post_content->post_content;
echo do_shortcode( $content );

and

$content = get_post_field('post_content', $post_id);
echo do_shortcode( $content );

I could add the script manually through a footer hook, but I would like it to be future proof. What is the best way to do that?

Thank you
