[ BUG ] GraphQL operation does not support variables when using abstracted keywords (IdentityProtection)

[jshcodes]

Describe the bug
When working with the GraphQL operation, you are unable to provide variables to the processor without leveraging the body keyword. variables needs to be added to this method as an allowed keyword.

To Reproduce
See additional context below.

Expected behavior
Variables can be provided to GraphQL without having to leverage the body keyword.

Environment (please complete the following information):

• OS: All supported
• Python: All supported
• FalconPy: <= 1.2.10

Is there a way to use GraphQL queries that paginate? I'd like a report that returns more than 1000 results (the limit without paginating).

I'm using IdentityProtection / falcon.graphql: https://github.com/CrowdStrike/falconpy/wiki/Identity-Protection

The response object contains 'hasNextPage' and 'endCursor' values to obtain the next page of results. How can I use this information to gather the next page of data?

response["body"]["data"]["entities"]["pageInfo"]["hasNextPage"] = True
response["body"]["data"]["entities"]["pageInfo"]["endCursor"] = eyJfaWQiOiIwMDAwdWJiOS01YzQxLTRmNzctODhmNy02MWFjOGQ1ZDViNztifQ==

An example graphql query that has pagination enabled is below. You'll note that I only have 'first' set to 2 so the output response is small and can be easily read for troubleshooting. However with pagination enabled, it should repeat batches of 2 results until all results have been obtained. Normally 'first' would be set to 1000.

    idp_query = """
      query ($after: Cursor, $enabled: Boolean)
  {
  entities(types: [USER]
    archived: false
    enabled: $enabled
    after: $after

    dataSources: [ACTIVE_DIRECTORY]) {
