Yes, I have tried the option you mention to edit the last commit with C-x C-e and it is working fine.
But It seems that it only allows amending the last commit if I have edited a file.
As I understand it I need to edit a file and then do vc-next-action to get to the log-edit buffer
where you can do C-x C-e.
I could not find a way to do this if just the commit message is supposed to be updated.

Yes. This feature seems unfinished, and it was never updated for the
newer VC systems.
However, we have an option for amending the last commit (press C-x C-e
in an already open log-edit buffer). It only works with Git and Hg now.
It would be good to unify these two features somehow.
