How to send pitch names to host piano roll from VST?


I am trying to set the pitch names of the piano roll of the host from my VST3 plugin.
Is it possible in JUCE?
My understanding was that I needed to implement the getMidiKeyName() of the VST SDK, however there is no reference to it in the JUCE documentation / discussions.
Am I wrong and should I need to look for something else?

Thank you!
