Docker: not found when running cmds in jenkinsfile

Question

I am new to docker and CI. I am trying to create a jenkinsfile that would build and test my application, then build a docker image with the Dockerfile i've composed and then push it into AWS ECR. The steps I am stuck on is building an image with docker, i receive and error message docker: not found. I downloaded docker plug-in and configured it in the global tool configuration tab. Am i not adding it into tools correctly?

There was another post wear you could use kubernetes to do that however kubernetes no longer supports docker.

image of how i configured docker in global tools config: global tool config
