Monika,
Good Morning, I searched HW and only came up with a few threads that ask the same questions that you have. I know we have had a few posts re the topic in the past but no solid info that I could find.
Let us hope one of our current members or a new member will come along that has more info on this topic.
I wish you well and hope to see an answer to your question.
Kindly,
Kitt
