How to use the react-relay-network-modern/es.RelayNetworkLayer function in react-relay-network-modern

export default function createNetwork(
  subscriptionClient: ManagedSubscriptionClient,
  tokenGetter: TokenGetter,
  clientID: string
) {
  return new RelayNetworkLayer(
    [
      customErrorMiddleware,

        clearOnMutation: true,
      }),

        url: () => Promise.resolve(graphqlURL),
      }),
      retryMiddleware({
        fetchTimeout: 15000,
        retryDelays: (attempt: number) => Math.pow(2, attempt + 4) * 100,
        // or simple array [3200, 6400, 12800, 25600, 51200, 102400, 204800, 409600],

        beforeRetry: ({ abort, attempt }) => {
