Hi,
I created new image from grafana:7.3.7 and the plugin does not apear in the list
the docker looks as follows:
from grafana/grafana:7.3.7
RUN grafana-cli plugins install grafana-worldmap-panel

i see the plugin within the instance, however not picked up..:
bash-5.0$ ls /var/lib/grafana/plugins
grafana-worldmap-panel
any idea?
Thanks,
Amit
