And maybe you need to define types for logger cb function?

    const logger = ({
      state: { queries, mutations },
      dataWithOptimisticResults: inspector,
    }: {
      state: {
        queries: any;
        mutations: any;
      };
      dataWithOptimisticResults: any;
    }) => {
      counter++;
      enqueued = {
        counter,
        queries,
        mutations,
        inspector,
      };
      if (currentConnection !== null) {
        currentConnection.send('broadcast:new', enqueued);
      }
    };
    client.__actionHookForDevTools(logger as () => void);

Yeah all of this would benefit from typing properly, so go ahead if you are able to figure out the types!
