Need help with pagination for GraphQL integration …

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)
