Cockpit custom dashboard menu entry

Im trying to add a custom menu entry in Camunda Cockpit, just like the one shown below:

Im using springboot 2.0.3 with camunda-bpm-spring-boot-starter-webapp 3.0.

I would like my custom plugin to be shown when i click on the new menu entry.
I know the idea of plugin points, so know i can bind my custom plugin with the view like : viewsProvider.registerDefaultView(‘cockpit.MYNEWMENU.view’)

But first i need to create the new entry and make it a plugin point. How can i do that?
Obviously i could easily add it in the camunda webapp sources and build a war out of it, but as i said im using camunda-bpm-spring-boot-starter-webapp (so i would prefer not to create the war myself).

Can i do it somehow with a plugin? Unfortunatelly i could not find any information in the documentation (there is an example of sample-plugin but it binds to “camunda.dashboard”" page)

Thx for help.
