Currently when Zoom function is set to active on Proton it creates some kind of generic Zoom link in the meeting appointment, but doesn't allow for the integration to an existing pro Zoom account. It causes meetings to be created with links that the client has that is different to the one that I have in my calendar. Likely the integration of a non Google or Outlook account is required. There is a request for some kind of URL (EWS URL from memory) to link non-Google or Outlook clients but there is nowhere in the settings on the Proton dashboard or settings to find that URL. None of the help topics cover this either and don't own up to the fact that this might be a totally missing function with Proton - a very badly needed and basic requirement of making a meeting invitation these days. A super necessary feature.
