Need help with pagination for GraphQL integration to Power BI

Hi Guys, I am pretty new to GraphQL API integration to Power BI. 

I read an article Connect Power BI to the Dimension Four API | Dimension Four and able to use my GraphQL code perfectly. (I used Template 2 from this link). But there is a pagination issue in my API. My initial call will retrieve only first 200 rows. I have to include pagination in my M code to retrieve all the rows from the API call. I desperately need your help since I have no clue on how to achieve this in M.

let
	url = "https://iot.dimensionfour.io/graph",
	tenant_id = "your-tenant-id-here",
	tenant_key = "your-tenant-key-here",

    GraphQL_Query = "{""query"":""

    {
        points{
            id
            name
        }
    }

""}",

    Query_SingleLine = Text.Clean(GraphQL_Query),

    Source = Web.Contents(
    url,
    [
             Headers=[
                 #"Method"="POST", 
                 #"Content-Type"="application/json", 
                 #"x-tenant-id"=client_id, 
                 #"x-tenant-key"=client_secret
                 
                 ], 
                 
                Content=Text.ToBinary(Query_SingleLine)
                 
                 ]
    ),

    #"JSON" = Json.Document(Source)
