How can I set/change the state of an entry within the calendar

We are using CalDAV as shared calendar. Some of us are using Sunbird/Lightning. Within Sunbird, you can set the state of a calendar entry to tentativ, confirmed, …
eM Client shows this information, but I can not change it or set it in my own entries. How can I do that?

you can do this by right clicking the event and select Accept / Decline or Tentative.

I hope this was a helpful answer,

Not really. This sets another bit within the ics. E.g. the status says tentative, the right click say booked.

Hi, can you please provide a screenshot of the issue.
The application should really only have the states Accept/Decline/Tentative.

Thank you,
