Grouping based on latest date

I have this table, make like this:

let
    Source = Sql.Database("mantleanalytics.database.windows.net", "Hevold_Dev"),
    dbo_rate_oslo_all = Source{[Schema="dbo",Item="rate_oslo_all"]}[Data],
    #"Filtered Rows" = Table.SelectRows(dbo_rate_oslo_all, each [Start_Date] <= Date_oslo and [Stop_Date] >= Date_oslo),
    #"Pivoted Column" = Table.Pivot(#"Filtered Rows"[[Port_of_Loading],[Shipping_Line],[40DC]],{"MSC","COSCO","YANGMING","HAPAG","CMA-NAK","CMA-CGM"},"Shipping_Line","40DC",each List.Min(_))
in
    #"Pivoted Column"

However, I now need to pivot based on latest date and grouped by "Shipping_Line", "Port_of_Loading", "Port_of_Discharge".
I have tried to do this:

let
    Source = Sql.Database("mantleanalytics.database.windows.net", "Hevold_Dev"),
    dbo_rate_oslo_all = Source{[Schema="dbo",Item="rate_oslo_all"]}[Data],
    #"Filtered Rows" = Table.SelectRows(dbo_rate_oslo_all, each [Start_Date] <= Date_oslo and [Stop_Date] >= Date_oslo),
    #"Filtered Rows1" = Table.Group(
        #"Filtered Rows", 
        {"Shipping_Line", "Port_of_Loading", "Port_of_Discharge","20DC"}, 
        {
            {"max_start_date", each List.Max([Start_Date]), type nullable date}
        }
    )
in
#"Filtered Rows"

But I cant get it to pivot based on the max date.

This how i tried it:

let
    Source = Sql.Database("mantleanalytics.database.windows.net", "Hevold_Dev"),
    dbo_rate_oslo_all = Source{[Schema="dbo",Item="rate_oslo_all"]}[Data],
    #"Filtered Rows" = Table.SelectRows(dbo_rate_oslo_all, each [Start_Date] <= Date_oslo and [Stop_Date] >= Date_oslo),
    #"Filtered Rows1" = Table.Group(
        #"Filtered Rows", 
        {"Shipping_Line", "Port_of_Loading", "Port_of_Discharge","20DC"}, 
        {
            {"max_start_date", each List.Max([Start_Date]), type nullable date}
        }
    ),
    #"Pivoted Column" = Table.Pivot(
        #"Filtered Rows1"[[Port_of_Loading],[Shipping_Line],[20DC]], 
        {"MSC","COSCO","YANGMING","HAPAG","CMA-NAK","CMA-CGM"},
        "Shipping_Line",
        "20DC",
        each List.Min(_)
    )
in
    #"Pivoted Column"

If there is any help i would really appreciate it
