Synology DSM Integration: Home Mode switch is missing?

Hi,
I installed the Synology DSM Integration to my Home Assistant Supervised installation, and everything seems to be working fine except that the Switch for enabling / disabling the Surveillance Station Home Mode is not added.
Does anybody have an idea why this is, and how I can still add this?
I created a special administrator user on the NAS that does not have access to any filesystem nor application on the NAS, as is recommended on the Integration site.
Could that be the cause? Should this user have access to the Surveillance Station application?

Never mind: luckily I answered this question myself :grinning:
It indeed was required to give this special user access to the Surveillance Station application on the Synology NAS.
As soon as I added access right for this application the Switch was automatically added!
