Hide query source panel of shared query

I managed

So far, so good.
Now I would like to hide the source panel.
The data retrieved is a superset of the data for the user targeted panels.
Thus it looks quite messy and confusing.

I can’t find a option to hide a panel.
I might hide the query, but then the data are not available for the other panels as well.

simple workaround for the moment:
just move the collector panel to minimal size and add Description “nothing to see here”
