Dynamic - Grouping by a Measure column - combining the text values

I have a table "School" :

School
ClassNamesCounts
c1XXX1
c1YYY2
c2ZZZ3
c2AAA4
c3AAA2
c3BBB3
c4BBB2
c5CCC0
c5CCC1
c5DDD2
c6FFF1


I have created a 'Total Counts' groupby 'Names' column & created Rank based on 'Total count' Measure.

NamesTotal countsRank
AAA61
BBB52
ZZZ33
DDD24
YYY24
CCC15
FFF15
XXX15


I wanted to create a 'new column' called 'Updated Names' which concatenate the value as shown in the below table based on 'Total Counts' column (Dynamically Grouping by a Measure column - combining the values)

Expected output 
Updated NamesTotal countsRank
AAA61
BBB52
ZZZ33
DDD,YYY24
CCC,FFF,XXX15

    Hi Anonymous ,

     

    When you complete this step, write the following statement in the advanced editor, then sort in descending order and add an index column. The index column is your Rank column.

    let
        Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("XctLCsAgDEXRvWTsoH7auVFcg4k46v730AeKgU4uj0MyBr2eHPXeUU/TbRARNCwImKqKRoOcM5oWxAPBgJntJR3YFzdmKQW9/uANaq328mC21tbF/AA=", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [Class = _t, Names = _t, Counts = _t]),
        #"Changed Type" = Table.TransformColumnTypes(Source,{{"Class", type text}, {"Names", type text}, {"Counts", Int64.Type}}),
        #"Grouped Rows" = Table.Group(#"Changed Type", {"Names"}, {{"Total counts", each List.Sum([Counts]), type nullable number}}),
        #"Combined Values"= Table.Group(#"Grouped Rows" , {"Total counts"}, {{"Combine Values", each Text.Combine([Names], ","), type text}}),
        #"Sorted Rows" = Table.Sort(#"Combined Values",{{"Total counts", Order.Descending}}),
        #"Added Index" = Table.AddIndexColumn(#"Sorted Rows", "Index", 1, 1, Int64.Type),
        #"Renamed Columns" = Table.RenameColumns(#"Added Index",{{"Index", "Rank"}})
    in
        #"Renamed Columns"

    Anonymous Well, maybe a measure like:

    Measure = 
      VAR __Rank = [Rank]
      VAR __Table =
        ADDCOLUMNS(
          SUMMARIZE('Table',[Names],"Counts",SUM('Table'[Counts])),
          "Rank",[Rank]
        )
    RETURN
      CONCATENATEX(FILTER(__Table,[Rank]=__Rank),[Names],",")
