How can we delete automatic generated slack posts when adding a Guru card link in a post?

I believe you have to remove Guru from the specific Channel that you don’t wanted automated posts. I only add Guru to certain channels where we share alot of cards and knowledge in.
Thank you

Also, we’re releasing an update soon that will allow the user who posts a Guru Card link to remove the unfurled post.
