II want to buy a Power Pages license to create a test website for my learning. The site must have only one authenticated user, which will be myself. I need to create, modify, and delete records in my Dataverse database through the site, and also create Power Automate flows and trigger them from my Power Pages site. I've already purchased a Power Apps Premium license and a Power Automate Premium license. Now I want to buy a Power Pages license for a single authenticated user that won't be too expensive. Please tell me which license is suitable for my needs. Thank you.
