Power Automate Licensing (Process vs. Premium)

Question

I am an RPA developer new to the Power Automate Platform.

From the documentation I read that the Process (bot/month) license provides the option for Unattended robots and the Premium (user/month) for attended robots.

Having the need to use the Unattended Robots for my Use Case, I purchased the Process license, however accessing my Power Platform environment I see that I cannot use features such as queues. In order to use those features it asks me to activate a Premium license.

Hence the question:

• Since to be able to define flows in Power Automate Desktop and monitor the status of queues in Power Automate Platform requires the Premium license, and since to schedule flows on a Robot machine requires Process license, does this mean that for each development environment (DEV, TEST, PROD) both the Premium and Process licenses are required?

I look forward to figuring out what licenses to purchase in order to have full functionality available to develop and and run Unattended RPA robots.

Note:

• A reference to the official documentation is also appreciated.

Thanks in advance
