What license do I need for Microsoft Sentinel?

Hello there, I'm curious about the licensing requirements for Microsoft Sentinel. Can you please explain to me which license is necessary in order to use Microsoft Sentinel effectively? I'm assuming it's not a standalone product and might require a certain type of Azure subscription or something similar. If so, can you clarify the specific subscription or license type that I would need to procure in order to access and utilize the full functionality of Microsoft Sentinel? I appreciate your time and expertise in this matter.
