How do I find my GFI?

Could you please elaborate on how one can locate their Governance Forum Index, or GFI? I'm particularly interested in understanding the steps involved in identifying and accessing this metric. Is there a specific platform or tool that provides access to GFI data? Additionally, is there any prerequisite information or knowledge that one needs to possess before attempting to find their GFI? Any guidance or insight you could provide would be greatly appreciated. Thank you for your assistance in navigating this process.
