Rui has posted about this add-on before, and gave the download link here: https://nvda.groups.io/g/nvda/message/77303 

The version that downloads from the link in the above noted message is compatible only through NVDA 2020.4.  I do not recall whether he has mentioned an intent to update for NVDA 2021.1 or not. There's a lot of water flowing under the various 2021.1 bridges these days.

I do not understand why some seek to separate a person from their actions.  The self is composed of an individual’s thoughts, actions, and expression, which are contained in and actuated by the body.  What you do and say is the clearest indicator of who you are.
