Greyhawk Initiative, does the DM declare monster actions to the players?

@mikemearls Can't wait to try the new Greyhawk Initiative UA rules! Question though, RaW does the DM declare monster actions to the players?

Dungeon master should try to give hints, based on what PCs can see and understand. Might be a good use of insight at start of round. https://t.co/Pf2P5kppAn
