Question I need some help figuring out why I cant create a brain within my unity project.

So what I am seeing is that I have ml-agents installed I cannot guarantee this is correctly done I followed steps provided. under package manager I see the ml agents and its showing installed.
Also under the project folder it shows up in packages.
However, when I right click and try to create the brain I do not get the ml-agents tab where I would select the brain type what might I have done wrong?
