Kanboard calendar to Google Calendar : iCal feed URL not available


I used Kanboard with Framaboard.

As described in the documentation, I would like to copy and paste the iCal feed URL from Kanboard to Google Calendar.

Yet, I did not obtained any ICal feed URL but a .txt file which did not contain one (or I did not find it) :

Please, could you give me advices about this option of Kanboard ?

Thanks in advance for your return.

The iCal url is the one in the link. Instead of clicking on it, try to right click -> copy url or copy link, something like it

It works (right click > copy URL > paste it in Google Calendar.
Thanks a lot
