Opensearch Dashboards Maps - How install and configure visual dashboard-maps

Opensearch 2.7.0 Dashboards

I have a working Opensearch 2.7.0 environment up and running since earlier, and now i am trying to get the graphical Maps function to work but I am not able to.

When I choose Create Map in the GUI I only get a completely blank screen (logged in as local admin)

Read about different plugins and also tried to install the dashboards-maps-2.7.zip but it fails with:

./opensearch-dashboards-plugin install file:dashboards-maps-2.7.zip
Attempting to transfer from file:dashboards-maps-2.7.zip
Transferring 245363 bytes…
Transfer complete
Retrieving metadata from plugin archive
Plugin installation was unsuccessful due to error “No opensearch-dashboards plugins found in archive”

Which plugin/s do I need and where do I find them ?

Best Regards
