Filtering nested groups - Power Query M

Hi All,

I am having trouble filtering the column [Source] within my nested group table "Grouped".

My condition should check whether the value "SAT" exists in the column, if true it will remove rows with values "VBRP", else column will remain as is.

Code is as follows:

= Table.AddColumn(#"Grouped Rows", "FilteredTable", each Table.SelectRows([Grouped], each
if Text.Contains([Source],"SAT") then [Source] <> "VBRP"
else true
))

Thanks!
