Combine each item in list of lists

[smpa01]

My source data is following

= {{"A","B"},{"C","D"},{"X","Y","Z"}}

From there, I want to land up here

 I can do this by doing following

let
    Source = {{"A","B"},{"C","D"},{"X","Y","Z"}},
    Loop = List.Generate(
                          ()=>[i=0,j=Source{i},k=Text.Combine(j,",")],
                              each [i]<List.Count(Source),
                              each [i=[i]+1,j=Source{i},k=Text.Combine(j,",")],
                              each [k]
    )
in
    Loop

Is there any other way to achieve the end goal other than using List.Generate? maybe by using List.Transform?

let
    Source = {{"A","B"},{"C","D"},{"X","Y","Z"}},
    combo = List.Transform(Source, each Text.Combine(_,","))
in
    combo
