A paper with an identical title was published at an IEEE conference. The conference took place in November 2023, a month after the offer was published. The number of co-authors also matches the offer. The offer sold the 6th co-authorship slot, and the paper also has six co-authors. Thus, there are four matches between the published paper and the offer: title, publisher, number of co-authors, and publication date (after the offer).
