Format Web Service Data into a Table

I am having issues needed to make a table of 3 columns from a REST API response using Power Query M language.

Below is my code ( at the end of which my table 'newTable' still remains empty.

let
    Source = Json.Document(Web.Contents("https://admcorpdev.service-now.com/api/now/stats/incident?sysparm_query=active%3Dtrue%5EpriorityIN1%2C2&sysparm_count=true&sysparm_group_by=caller_id.location.u_region%2Cpriority")),
    result = Table.FromRecords(Source[result]),
    newTable = #table(
        {
            "Priority",  
            "Region",
            "Count"   
        },
        {}
    ),
    TableSource = Table.Buffer(result),
    data = List.Generate( 
        () => [x=0],
        each [x]<= Table.RowCount(result),
        each [ 
            //Generate a new Table and append fields into it
            newTable = Table.InsertRows(newTable,1,{[Priority = "2", Region ="NA",Count = "56"]}),
            x=[x]+1] 
    )
in
    newTable

So i have mixed bag of List and record in my data coming in which i want to load in one table with 3 fields.
