How do I auto-provision a role?

Summary:

We would like to auto-provision the termination role. How do I set that up?

Content (required):

We have a custom termination role and we would like to auto-provision the role so that when a termination action is approved, the terminated employee automatically gets the termination role. Additionally, when that happens, we would like to remove the other roles, i.e.employee role. How do we set this up so it happens automatically instead of the HR team having to manually add and remove the roles upon termination?
