Is there any API for getting the installed app list?

sadly

{
  appInstallations (first: 100) {nodes {
    id 
    app {title}
  }}
}

returns

{
  "errors": [
    {
      "message": "access denied",
      "locations": [
        {
          "line": 2,
          "column": 3
        }
      ],
      "path": [
        "appInstallations"
      ],
      "extensions": {
        "code": "ACCESS_DENIED",
        "documentation": "https://shopify.dev/api/usage/access-scopes"
      }
    }
  ],
  "data": null,
  }
}

… any suggestions?
