Power Query group by one column and concatenate string values of another column

I needed an example of how to group by one column and concatenate string values of another column.

Here is what this ended up like:
—
let
Source = #table({“Product”, “Customer”},{{ “Apples”,”Chris”},{“Apples”,”Fred”} ,{“Oranges”,”Chris”}}),
myCombine = Combiner.CombineTextByDelimiter(“;”),
#”Grouped Rows” = Table.Group(Source, {“Product”}, {{“Test”, each myCombine ([Customer]), type text}})
in
#”Grouped Rows”
