Magento 2.3 RMA – shipping labels and email notifications?

I can’t find this in the docs anywere, and I’m afraid that means it doesn’t exist natively. When a customer requests an RMA, is an email sent to the website admin? It seems not.
Also, when the RMA is approved by an admin, can the customer print a shipping label? All I can find on this topic is shipping label integration info for order shipments, but not RMA.

 

Thank you for your help!
