Add Maven role to existing user

Hi,
I installed the plugin and it seems to work, but I can’t find a way to add my normal wordpress user, the one I use to manage the whole website, to the Maven list of users. This means that everytime that I need to access the restricted area I have to log out and log in again with a user created for the plugin.

I checked in my profile, inside the wordpress admin panel, and while it lists some fields to add info, there is no way to add a Maven role.

Any help?
