The Recaptcha V3 plugin from numinix is something new and would be different than the other reCaptcha module in the plugins section. So before installing the one from Numinix I would uninstall the other.

I would assume on your other thread because the numinix module has unfortunate naming, using the "Recaptcha V3" which when you look at the google recaptvcha page on google has two versions, V2 and V3 it was assumed you were talking about this module related to this thread and not a new version by someone else that does only V3... make sense?
