security roles in ribbon

Hello experts,
I already learned about ribbon workflows, but another inconvenience arises, it turns out that I already need to hide the button depending on the role.
I'm following this tutorial:
www.powerobjects.com/.../solving-security-headaches-display-rules-based-on-security-roles

this way I have the ribbon configured.

this way I have the role configured.

PS: I have also created the entity.

any result would be very helpful,

thank you very much, greetings
