Magazines often have one shots that may later become full on series if the readers took enough interest in it. In fact, Usazaki's old work Asagaya Geijutu Koukou Eizouka e Youkoso(the other one listed under the "Other manga by the same author(s)" section) was the one shot that preceded Act-Age!
Iirc she collaborated with the writer at 18 years old and when Act-Age came out she was 22 which is VERY young for an author to debut and in a magazine as prestigious as Jump nonetheless! Being a female co-author for a series that is in a predominantly male industry makes her feat so much more incredible. It's unfortunate her debut series was put to a stop because of the writer....Thankfully JP fans were super supportive of her when the incident happened, but until this one shot came out she hasn't done any manga-related work since then.
Depending on how well the JP audience liked this one shot, give it a few years and there is a possibility for it to become a serialized series as well.
According to this tweet by Usazaki, this one shot was from the issue of Shounen Jump for the week of Dec 20, 2020.
