In a minor mode I wrote for myself, I use add-text-properties to make
certain things invisible. This does not work in org-mode, and I don't
understand why. For instance, the following has no effect in when the
buffer is in org-mode (and only when it's in org mode):
(add-text-properties 1 3 '(invisible t))
Any other text property I try to add does not give me any problem.
I have also tried to achieve the same by adding things to
buffer-invisibility-spec, but again, the following has no effect
whatsoever, if in org-mode:
(add-text-properties 1 3 '(invisible hide-this-stuff))
(add-to-invisibility-spec '(hide-this-stuff))
Can anyone give me a hint as to what is going on?
Thank you.

Maybe try this instead (you added the symbol as a list, not just a symbol):
123
#+BEGIN_SRC emacs-lisp
(add-text-properties 1 3 '(invisible hide-this-stuff))
(add-to-invisibility-spec 'hide-this-stuff)
#+END_SRC
#+RESULTS:
: (hide-this-stuff (org-hide-block . t) (org-link) (outline . t) t)
#+BEGIN_SRC emacs-lisp
(remove-from-invisibility-spec 'hide-this-stuff)
#+END_SRC
#+RESULTS:
: ((org-hide-block . t) (org-link) (outline . t) t)

This is because Org makes use of invisible text property during
fontification. You should either apply invisibility in Org through
font-lock, or do it temporarily until next re-fontification via
(with-silent-modifications (add-text-properties 1 3 '(invisible t)))
Best,
