Query Plan Tab missing with 'graphql-playground-middleware-express' playground

I am using Apollo Federation Server, as I need to run it using specific context path,

I am using plugin > ApolloServerPluginLandingPageGraphQLPlayground

All runs fine but “Query Plan” tab does not show up.

The query plan tab was a custom extension of the GraphQL playground. To get the best integration with federation and viewing the query plan, we recommend you checkout the new Apollo Sandbox:
