Pending workers, newly hired employees not receiving FYI notifications after transactions are approv

Add Pending Worker and Hire an Employee Workflow:

The requirement is that pending workers and newly hired employees should receive an FYI notification after the transactions are approved by the respective approvers. However, even after the approvers approve the request, the pending workers and newly hired employees are not receiving FYI notifications. Is this expected behavior, considering that user account creation and role auto-provisioning can take a few minutes?
