I am interested in installing a LibreOffice .oxt plugin for collabora server that I have installed using docker, The documents mention : unopkg add --shared \<plugin.oxt\>  
but this is does not work. Is the any way of installing this?

I tested installing one extension like this (replace those in square brackets with your extension & docker):

```auto
sudo docker cp ./[extension name].oxt [docker name]:/home/[extension name].oxt
sudo docker exec --user root -it [docker name] /opt/collaboraoffice/program/unopkg add --shared /home/[extension name].oxt

```
