The first option would be the best for me: because my use of org-mode is
mainly for my work and I am always pasting this link in new org file. It
is boring. If you  could me help to define such a hook,  I will be again
indebted to you. But  please do it only if it is  not time consuming for
you.

htmlize works  again now  in my  setup. Strangely  I saw  that I  had to
install jupyter...

Best wishes,
