Hi @TMarcianelli,
welcome back to the forum.
A role can be assigned or detected. For automatic assignacion, when an identity meets the necessary requirements, the role will be assigned on refresh. Into refrersh task you must mark this flag:
If you assigned a role through a request, the provisioning start automatically.
Into a BS role, is the same if you a script or a match list or a rule.
Also, if you want refresh on a identity you need to launch a workflow or an Identitizer(I dont know whot is it, I discover writing this post 
). In this topic, see the replies of @kjakubiak and @iamksatish.
