I have defined custom posts, and want to build a navigation at the end of each post like this (done this with a block based but none FSE theme before), need not be that specific, but at least I want a next post showing the the post title of that next post, considering the order defined:
before hover:
hovering:
and should consider the order I have entered at each cpt (in quick edit mode, top right):
And last but not least, should stop (not further navigation shown) when first one or last one is reached (for previous and for next respectively)
