Azure, to the best of my knowledge, does not offer any RPA services. I believe they are entirely focused on cloud service models such as SaaS, PaaS, and IaaS. You can contact the customer care team to gain a better understanding of this.
However, RPAaaS, a new technology, is in development (it's a new technology). RPA as a Service is a brand-new trend that's gripping the industry. Clients/customers can use RPA-as-a-service to obtain RPA services via the cloud. I'm not sure if Azure has this functionality.
