Problems paging sharepoint rest api

GetSharePointData:

(StartRow as number, rl as number) =>
    let
    Source = Json.Document(Web.Contents("https://companyz.sharepoint.com/_api/search/query", [Headers=[Accept="application/json", #"Content-Type"="application/json"], Query=[

                    rowlimit = Text.From(rl),
                    startrow = Text.From(StartRow)   // Usare il parametro StartRow qui
                ]])),
    Rows = Table.FromRecords(Source[PrimaryQueryResult][RelevantResults][Table][Rows]),
    #"Added Custom" = Table.AddColumn(Rows, "Custom", each let #"Removed Columns" = Table.RemoveColumns(Table.FromRecords([Cells]),{"ValueType"})
    in Table.Pivot(#"Removed Columns", List.Distinct(#"Removed Columns"[Key]), "Key", "Value")),
    #"Removed Columns" = Table.RemoveColumns(#"Added Custom",{"Cells"}),
    #"Expanded Custom" = Table.ExpandTableColumn(#"Removed Columns", "Custom", Table.ColumnNames(#"Removed Columns"[Custom]{0}))
in
    #"Expanded Custom"

Query:

let
    PageSize = 1000,  // Limite di risultati per ogni pagina
    MaxPages = 3,      // Ad esempio, otteniamo 3 pagine (cambialo secondo necessità)
    Pages = List.Transform({0..MaxPages-1}, each GetSharePointData(_ * PageSize,PageSize)), // Ottieni tutte le pagine
    AllResults = Table.Combine(Pages)  // Combina tutte le pagine in un'unica tabella
in
    AllResults
