I meant trying to implement the same UI as flyspell-mode
for spell-checking by harper.

I use Eglot code actions all the time, and they work nicely.

I know.  What I meant is trying to implement flyspell-like UI
specifically for autocorrection that e.g. displays a list
of suggested replacements, and after selecting a candidate
replaces a misspelled word with the selected candidate.

I don't know how easy is to customize Eglot actions
to implement a different UI for selecting an action
with some parameters (e.g. a list of corrected words),
and performing the action.

I have looked at this, but didn't finish testing:
