[Solved] iCal Binding - Add Channel

I am using the icalendar binding - it works with the predefined 2 channels (current and next).
How can I add more channels to the calendar - in the filter settings I set the maximum to 10.
But still only 2 entries are in the channel available.
Thanks for any help.

Just find a video explaining that the new channels are defined in the filter.

That is what the docs could have told you:
