Rendering Blocks Loaded Via AJAX

Hi

I created a page that has a scrollable column of post listings in the left column, and a single post in the right column. I look for clicks on the posts in the left column using jQuery and load the relevant post in the right column using ajax and jQuery. No page refresh. I do it primarily to prevent a refresh of the left column on page load.

Its working perfectly except for block editor items like a slideshow, or gallery. The required CSS and JS doesn’t seem to be written in page via the_content(). I found this:

and this:

https://stackoverflow.com/questions/72635660/inline-styles-for-gutenberg-blocks-not-rendering-when-content-fetched-with-ajax

Am I right in thinking blocks require inline css and js? When does that get added to the page? Can I force it? It seems like in my example above, when the page first loads, blocks are rendered on the post side, but when I add a post to the right side via ajax and jQuery, the blocks are not rendered. is wp_footer() the key?

Any advice, guidance, pointers, flicks in the ear (??), greatly apprecaited. Thank you!

Regards
Mike
