Search function for specific value

I am looking for an M code for a calculated column.
The aim is to search for the value "Yes" in the Type column,
where the ID must be the same. If so, the value "Yes" must be displayed, otherwise a null value.

On the picture you see the two columns I have.
And the orange column is the calculated column I'm looking for.

    #"Grouped Rows" = Table.Group(Source, {"ID"}, {{"All", each _, type table [ID=nullable text, Type=nullable text]}}),
    #"Added Custom" = Table.AddColumn(#"Grouped Rows", "Measure", each if List.Contains([All][Type],"Yes") then "Yes" else null),
    #"Expanded All" = Table.ExpandTableColumn(#"Added Custom", "All", {"Type"}, {"Type"})
in

I would never have come up with this myself. Your example was already successful. Now I'm going to apply it to my actual data table.
