Hi, trying to debug subscriptions and seeing following error. Dont know what to do

{
  "errors": [
    {
      "message": "Your GraphiQL createFetcher is not properly configured for websocket subscriptions yet. Please provide subscriptionUrl, wsClient or legacyClient option first.",
      "stack": "Error: Your GraphiQL createFetcher is not properly configured for websocket subscriptions yet. Please provide subscriptionUrl, wsClient or legacyClient option first.\n    at https://unpkg.com/graphiql/graphiql.min.js:83560:29\n    at async t4 (https://unpkg.com/graphiql/graphiql.min.js:77155:25)"
    }
  ]
}

This package is only a thin integration layer for https://github.com/graphql/graphiql/tree/main/packages/graphiql. Feel free to find out how to do subscriptions with that. If there is something we can do in this package to aid that usage, you can report back with your results and propose a pull request.
