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


but I could not find media directory in UCS in path


Above path is provided by official seafile manual for 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.
