Its E on PC to see the maps. You need to vote on the mission first, like you did. If you don’t see anything on E then you still need to vote on the mission (from the smaller table in the captain’s quarters).
I also had a hard time with getting missions, accepting them, opening maps, etc at first. So did a friend. Its not intuitive.
Also, getting multiple chicken coops, storing them, chasing after chickens with them and capturing the right ones takes some practice.
