Power Query - Add another column to Table.TransformColumns

Hello, I have a Power Query code to group the data. However, this is for two columns. Can anyone help me with the code to get another column?

let
    Source = Excel.CurrentWorkbook(){[Name="Table1"]}[Content],
    Group = Table.Group(Source, {"CHARACTER NAME"}, {{"Scenes", each Table.Distinct(_), type table [SCENE NUMBER=text, CHARACTER NAME=text]}, {"Count", each Table.RowCount(Table.Distinct(_)), Int64.Type}}),
    Combine = Table.TransformColumns(Group,{{"Scenes", each Text.Combine(_[SCENE NUMBER],", ")}})
in
    Combine
