Why don't mutations persist? (GraphQL)

I'm working my way through the GraphQL tutorial. I'm on the segment about mutations, which I am led to believe are used to CHANGE data on the backend. I made a new movie with the title 'myMovie' which returned a movie id of 'movie_4' (using the Apollo Launchpad offered in the tut). I then ran the query:

query {
  allMovies {
    id
    title
  }
}

And 'myMovie' was not listed in the response and there were only 4 movies listed (should be 5, now, right?) ids: movie_0 thru movie_3

Why did it not save/persist?

Thank you for your help.

I believe my issues was because I had not forked the project. I tried that and then got this error message in the 'run' frame:

{
  "code": 400,
  "message": "Compilation failed: Cannot find module 'graphql-extensions'",
  "error": "Cannot find module 'graphql-extensions'",
  "stack": "Error: Cannot find module 'graphql-extensions'\n    at Function.Module._resolveFilename (module.js:325:15)\n    at Function.WebtaskModule._resolveFilename (/data/sandbox/lib/module.js:25:27)\n    at WebtaskModule.require (/data/sandbox/lib/module.js:101:39)\n    at require (/data/sandbox/lib/module.js:136:21)\n    at /data/io/cbd8ed83-f350-4dcb-a7a6-c36373447433/webtask.js:113:29\n    at Object.<anonymous> (/data/io/cbd8ed83-f350-4dcb-a7a6-c36373447433/webtask.js:257:5)\n    at WebtaskModule.compileWebtask (/data/sandbox/lib/module.js:95:34)\n    at defaultJavascriptCompiler (/data/sandbox/lib/compiler.js:119:30)\n    at defaultCompiler (/data/sandbox/lib/compiler.js:128:16)\n    at /data/sandbox/lib/compiler.js:231:17"
}

So, I still can't run a persisting mutation...
