Example Request: Subscriptions with RedisPubSub

Hey, I would like to request an example of GraphQL Yoga Subscriptions with RedisPubSub and asynchronous filtering.

We managed to migrate from ApolloServer to Yoga, but we still have to rely on the withFilter Function from apollo. This is working fine, but it would be easier / cleaner if we could directly make use filter function from GraphQL Yoga. Like described here: https://www.graphql-yoga.com/docs/features/subscriptions#filter-and-map-values

import { withFilter } from 'apollo-server-express';
{
  Subscription: {
    testSub: {
      subscribe: withFilter(
        (root: any, args: any, context: GraphQLModules.Context) =>
          context.injector.get(testModuleConfig).pubsub.asyncIterator("TEST_TOPIC"),
        (root, args, context: GraphQLModules.Context) => {
          // Here we can filter
          return new Promise(resolve => resolve(true / false));
        }
      ),
    },
  },
}

@inc16sec filtering events is described in the advanced section in the Subscription documentation: https://www.the-guild.dev/graphql/yoga-server/v3/features/subscriptions#advanced
