How to not show dates after previous month

Hello,

I have the following table loaded in Power Query.

Here is the M code. The "Month End Date" is based only on the "Until" date column. But i do not know how to add some step/s to retain only the rows for which "Month End Date" which do not occur after the previous month, based on today's date. We are currently in April 2022, so the results should not include any rows with "Month End Date" as from 1 April 2022.

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("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", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [Name = _t, From = _t, Until = _t, Score = _t]),

    #"Changed Type1" = Table.TransformColumnTypes(Custom1,{{"Month End Date", type date}})
in

 Any help is much appreciated!
