GraphQL: Unknow directive include - graphql

Question

I am practicing using directives with Graphql in Nodejs. When in the Playground I want to use the #include directive, the Graphql client tells me: "Unknow directive include". This is my code:
query getChar($id: ID!, $withGames: Boolean!) {
getCharacter(_id: $id) {
_id
name
race
games #include(if: $withGames) {
_id
title
}
image
}
}
In my Query Variables I have:
{
"id": "5f945a7b24c84f35ecfae633",
"withGames": false
}
but I get the following error:
{
"error": {
"errors": [
{
"message": "Unknown directive \"#include\".",
"locations": [
{
"line": 6,
"column": 11
}
],
"extensions": {
"code": "GRAPHQL_VALIDATION_FAILED",
"exception": {
"stacktrace": [
"GraphQLError: Unknown directive \"#include\".",

]
}
}
}
]
}
}
What am I doing wrong?

It was a version problem of the graphql-tools. Checking the node_modules/graphql-tools/package.json file I observed that I was using version 4. I found here that version 4 had problems with the directives and the use of version 5 was recommended. This is what I did:
npm i graphql-tools#5.0.0
I restarted the server and refresh the Playground page and voila, I already have the #include directive and all the others available.
