Using the mediatopic.post method on a post post tagged "promo"?

Question

Classmates

Good afternoon.
I have a question, when using the mediatopic.post method for a post with the "promo" tag, this method returns the topic ID, but after moderation, this topic is deleted and a new one is created in the group's feed, with a new ID.
How can I get a new ID using the old one?
Or maybe there is some other way?
Thank you.
