Store static GeoJSON data for dashboard geomap layer


I want to add another layer to my geomap panel. The data for this extra layer is not stored in any database. All I have is a static .geojson file. is it possible to insert this geojson object within the json model of the dashboard or is there any other simple solution?

Check this section

Yes it enables to put the .geojson file in the public folder, however I dont have access to the Grafana installation. Hence, I wonder if its possible to add it to the dashboard itself or somehow through my login.
