Help needed to use this plugin

[SirineMaghraoui]

Hi, I installed this plugin using npm and I'm trying to use it with a chart. Now the problem is that when I use the example, the chart disappears. How can I import the plugin type of this lib so I can use it like : "DoughnutLabelPluginTypeExample"

options: {
    plugins: {
      doughnutlabel: {
        labels: []...
        ....
    }
  }
},
plugins:[DoughnutLabelPluginTypeExample]
