Hi,

I am creating a custom plugin for Kibana, and I am running into an issue with the plugin registration feature in this documentation: [https://www.elastic.co/guide/en/kibana/current/development-plugin-feature-registration.html](https://www.elastic.co/guide/en/kibana/current/development-plugin-feature-registration.html)

When I try to look at the plugin after I installed I get the error:  
`TypeError: Cannot read property 'myPlugin' of undefined`

I have added to my code the registration code:

```auto
    init(server) {
      const xpackMainPlugin = server.plugins.xpack_main;
      xpackMainPlugin.registerFeature({
        id: 'myPlugin',
        name: 'My Plugin',
        icon: 'merge',
        navLinkId: 'myPlugin',
        app: ['myPlugin', 'kibana'],
        catalogue: ['myPlugin'],
        privileges: {
          all: {
            savedObject: {
              all: [],
              read: [],
            },
            ui: ['show'],
          },
          read: {
            savedObject: {
              all: [],
              read: [],
            },
            ui: ['show'],
          },
        },
      });
    }

```

and the code to utilize the boolean to show a feature or not:

```auto
    import { uiCapabilities } from 'ui/capabilities';

    const show = uiCapabilities.myPlugin.show;
    if (show) {
      // show feature
    }

```

Is there some setup or configuration that I am missing in order to use uiCapabilities and have it defined?

@npm_install Welcome to the forum!  
We've been migrating the entire codebase and API's have changed. If you've created your plugin using the [plugin generator](https://www.elastic.co/guide/en/kibana/current/development-plugin-resources.html#_plugin_generator), then following the guide given in the docs should get you to a basic plugin that you can further develop on. If you haven't, try that, it should work.
