[xwiki-users] Extension manager usage with offline instance

Hello, I have a xwiki 7.0 instance without internet connection, so I have to manually install the extensions using xar archives. The manually installed extensions don't appeared in "Installed Extensions" menu of the extension manager. Can you tell me if this is normal ? Also, can you tell me how to cleanly uninstall manually installed extensions ?
