How to post products in OK without posting to the group feed?

Question

Classmates

I use the market.add method, but after publication, users receive a notification and a new entry appears in the group feed. And we are going to place several thousand goods, and this will lead to littering of the tape and anxiety of customers.

Tell me, how can I make sure that when a new product is posted, a new entry does not appear in the group feed?
