Is there a hook to insert content after a featured post in an archive?

Hi there,

Is there a hook to insert content after a featured post in an archive?

I don't believe there are any hooks positioned inside the posts/query loop on the archive pages.

or if I need to make template parts and add the content in the featured post template part.

That will likely be the way I think - it might be worth checking with WP's support team to see if they have any pointers.

Hope this helps.
