how to attach note to arrows in state diagram

Question

I would like to attach a note to state-transition(or its text) in the state diagram. How can I do it?
The documentation describes only a note that is attached to specific state and "floating" note that cannot be aligned on a complex diagram.

Hello L.,

Adaped from: https://forum.plantuml.net/7855/notes-on-arrow?show=7858#a7858

We can use (tested on v1.2020.15):

@startuml
[*] -> State1
State1 --> State2
note on link
  this is a state-transition note
end note

If that can help,
