Cannot serve request to /content/graphiql/ in org.apache.sling.servlets.get.DefaultGetServlet
I want to use GraphQL for a poc. I am reffereing to this documentation.
I don't see GraphQL persistent Queries option in my configuration under Tools > General > Configuration browser nor I see any GraphQL option under Tools > Assets.
I tried installing the GraphiQL interface from this link But now if I am trying to access http://localhost:4502/content/graphiql/ I am getting the below issue.

I have AEM v6.0 on my local. Is there something else I need to do to use GraphiQL?
