Video in collabora | impress within nextcloud

Hey there,

after searching for a solution to insert a video in impress, i have found this docs:
https://help.collaboraoffice.com/6.0/en-US/text/shared/01/moviesound.html?&DbPAR=CHART&System=UNIX

Unfortunately, i am not able to integrate a video like this, because the feature “media” is not available.

Does anyone have collabora hosted within nextcloud? Is there maybe some difference between nextcloud office and collabora?

Versions are Nextcloud Office 5.0.7 and Nextcloud Hub II 23.0.7 Enterprise

Greetings,
Chris
