How to install GraphQL in AEM 6.5
I want to setup GraphQL in AEM 6.5 for which I installed latest service pack that is 6.5.13. I read that GraphQL is included in 6.5.10+ But after installing 6.5.13 I can not access GraphQL interface. (http://localhost:4502/content/graphiql.html). Below is the screenshot

I also tried to download and installed cfm-graphql-index-def-1.0.5 from software distribution but no result. Can anyone tell me how to setup Graphql in aem AEM 6.5
