Univention Corporate Server -> Seafile /seahub/media mising

Hello I use Univention Corporate Server (UCS) and I installed seafile by app center in UCS.
I want to create vhost for cloud-domain.com (for non root domain purpose /seafile) by this tutorial

https://seafile.gitbook.io/seafile-server-manual/deploying-seafile-under-linux/other-deployment-notes/deploy-seahub-at-non-root-domain

but I could not find media directory in UCS in path

/var/lib/univention-appcenter/apps/seafile/data/seafile-data/seafile.

Above path is provided by official seafile manual for UCS:

https://de.seafile.com/support/administratoren/documentation-seafile-app-ucs/

Can anybody help me?

I know that tutorial for create vhost is old and I already use updated vhost in my original debian 9, everything works fine in debian but in UCS seafile (downloaded via app center) is changed directory struct I guess.
