Installed but invisible in the panel list

[SunboTax]

Hello,

I've followed steps in the build.md. Every step goes well but when I signed the plugin and move it into the dir /var/lib/grafana/plugins/, this plugin doesn't appear in the front-end website page, even after i restarted the container of grafana.

bfc3fee8f619:/usr/share/grafana$ grafana cli plugins ls
installed plugins:
globalnoc-networkmap-panel @ 1.1.4
satellogic-3d-globe-panel @ 0.1.1
flaminggoat-maptrack3d-panel @ 0.1.9
bfc3fee8f619:/var/lib/grafana/plugins/globalnoc-networkmap-panel$ cat plugin.json
{
  "type": "panel",
  "name": "Network Map",
  "id": "globalnoc-networkmap-panel",

  "info": {
    "description": "GlobalNOC Network Map Grafana Plugin",
    "author": {
      "name": "GlobalNOC",
      "url": "http://globalnoc.iu.edu"
    },
    "keywords": ["network-map", "map", "network"],
    "links": [

    ],
    "version": "1.1.4",
    "updated": "2019-09-03"
  },

  "dependencies": {
    "grafanaVersion": "3.x.x",
    "plugins": [ ]
  }
}

Any hint, advice or solution would be greatly appreciated!
