Both is important. And related. Documentation needs to be discoverable. I was amazed when I tried jj (jujutsu, the "new git") and it popped me into some kind of weird textual user interface after executing `jj split` and I felt lost. I guessed, pressing `?` won't hurt and it told me just to use the mouse. The menues showed the related hot keys.
But the actual documentation of the tool has room for improvement. I needed a YouTube video to get started and that's rare for me.
So what I want to say is, that you need an intuitive, discoverable UI, but also a documentation that has each case (and if it's just for linking in 1st level support cases) _and_ is discoverable. And by that I mean both easy to grasp (e.g. following https://diataxis.fr/) and also can actually be found. I've had cases where a tool had good documentation, but actually finding it was the hard part.
