One can use :results file link without :file header argument.

#+begin_src bash :results file link
echo -n "~/Downloads/wallpaper.png"
#+end_src

#+RESULTS[9c92ca9d7a3cce34ddcc4714ea917225be60e080]:
[[file:/home/yantar92/Downloads/wallpaper.png]]

I now clarified this on main
https://git.savannah.gnu.org/cgit/emacs/org-mode.git/commit/?id=b2adb68af

Hope it clarifies how to achieve what you want without advice.
