Existing knowledge management functionality like XWiki/Confluence

Hi All,
is there a functionality/app to realize knowledge management, like you know that from Atlassian Confluence and XWiki?

What would I like to realize in concrete?
I need a documentation platt, with which I can document my knowledge points in structure. Furthermore I will use nextcloud file cloud and wanna arrow in my documentation to a specific file/directory in the nextcloud file cloud.
Is there such a functionality for knowledge management documentation? In case of yes, how is the name in nextcloud?


Have you already had a look at the Collectives app? Seems to be a good start in this direction https://nextcloud.com/blog/nextcloud-22-introduces-knowledge-management/
