It doesn't seem the Apollo client send `subscribe` via websocket event type

I am using this solution to setup graphql subscription in a lambda. But this code confused me:

https://github.com/reconbot/graphql-lambda-subscriptions/blob/main/lib/handleWebSocketEvent.ts#L44

When I test it by using ApolloClient in node, the client doesn't send a message type subscribe, instead it sends start. Is there anything wrong in the websocket event handler or should I change anything in client side to follow this message type?

This was built to be used by graphql-ws I don't know how to modify ApolloClient, but maybe we could support both if they are compatible enough.
