Completed? They only took Kherson city. The other 60% is fully under Russian control and good luck getting across the Dnieper to try and get it back.
You don't have to cross the river to take the rest or Crimea. As you well know, there is another province to the east of Kherson. I heard Ukrainians plan to take it. From there they can move westward. No need to cross the river.
It seems that Russia gave up the entire northern part of Kherson. I guess it is no longer a Russian territory.
One step at a time.
