Load block in template

Hello,
I’m trying to load a block created in lazybloc directly in the template in my theme.

Actually I’ve put this in the php

$reuse_block = get_post( 84 );
$context['block'] =apply_filters( 'the_content', $reuse_block->post_content);

And in the twig template
{{ block}}

But the block don’t appear. Am I missing something? Is it even possible to do that?

Thanks in advance
