Is Hawkgirl actually in Peacemaker Season 2?

 Hawkgirl made an appearance in the trailer for Peacemaker Season 2 a few weeks ago and many people have been talking about her involvement in the Peacemaker series. I have heard that James Gunn himself apparently has said that Mister Terrific and Hawkgirl are added to the series. However, from past experiences, it would be nice to hear something more definite soon. But even then, judging from past DC projects, it's questionable.
