Query in overpass-turbo for geometries with certain number of nodes

I make a query with house number 14 and get several results, e.g. overpass turbo

Question: How do I have to design the query so that only objects with a certain number (e.g. 7) of nodes are returned? In the example above, I only want objects that consist of 7 nodes. This should only leave the house at Dr.-Clemens-Pirquet-Straße 14.

test something like this (6 members/nodes+“member/node to close way”)

way["addr:housenumber"="14"](if:count_members() == 7)({{bbox}});
out geom;


Wow, exactly what I asked! Thank you very much!
