Open Distro for Elasticsearch as plugins


Hello guys !
I’m trying to install only the plugins to initial Elasticsearch v6.6.2 installation.
For instance, I managed to install opendistro elasticsearch security plugin but I think the installation lacks Kibana open distro security plugin.
There is no Kibana Open Distro login page, no security management interface. Only an alert window similar to the one to connect to elasticsearch.

Am I wrong?
I tried the elasticsearch oss version too.

Thank you a lot anyway!
