Is there any way to pass authorization token to subscribe dynamically?

How to add authorization token in below query dynamically. This would be useful in testing cases.

apolloClient.subscribe({
  query: gql`
    subscription onNewItem {
        newItemCreated {
            id
        }
    }`,
  variables: {}
}).subscribe({
  next (data) {
    // Notify your application with the new arrived data
  }
});
