I have the following test-setup here:
I have a UCS with Kopano, NextCloud and Collabora installed.
Integration of Collabora into NextCloud went fine, I can create / edit documents without problems.
Integration of Nextcloud into Kopano via files Plugin worked as well. I can see and Share Files.
Hower what I am not able to accomplish is to access the Collabora suite from within the Kopano itself to be able to edit files. I always have to login to nextcloud and go from there.
Does anyone have experience with this or an idea how I should approach this? Am I missing a plugin to be able to accomplish Collabora integration to Kopano?
