Issues with kibana_markdown_doc_view plugin

[HH2O77]

Hi All,

I am trying to use the kibana plugin:

sw-jung/kibana_markdown_doc_view

The latest version supported is 6.2. I am trying to installed after changing the version in 6.5 but I got an error with LESS when installing. If anyone has any idea how solve the problem. I fairly new in kibana plugins and the documentation seems to be scarce.
