Ros2 Attribute Error no attribute kill

edit

I made a custom service where I use the /kill function from turtlesim but for some reason the package can't find the /kill service at all because when I call service list the option does not appear. I added

from turtlesim.srv import Spawn, Kill, TeleportAbsolute, SetPen
from turtlesim.msg import Pose

to my node file and call the service in the node file like:

self.kill_future = self.kill.call_async(Kill.Request(name="turtle1"))

I also have

find_package(turtlesim REQUIRED)

in my Cmake file and

 <build_depend>turtlesim</build_depend>
 <exec_depend>turtlesim</exec_depend>

in the package.

Am I missing something?
