ORC Onboarding - creating user account in Identity Provider

Summary:

How are you streamlining the process to get the IdP the account information of the new employee created

Content (required):

We are using a separate process for our HR team to notify stakeholders, including the Information Technology department, that a new employee will be starting (or terminating), where an account needs to be created in our IdP, Microsoft Active Directory or Azure. There has to be a better way to push that information for the IdP to create the account based on the employee's name. Our accounts are firstname.lastname@domainname. Please share how your organization handles this process.
