What is the total supply of Helium IoT?

Excuse me, could you kindly clarify the total supply of Helium IoT tokens? I understand that Helium is a decentralized network designed to power the Internet of Things, but I'm curious about the specifics of its token economics. Is there a finite amount of Helium tokens in circulation, or is there a mechanism in place to adjust the supply based on demand? I'm interested in knowing how this affects the potential value and adoption of the Helium network. Thank you for your time and consideration.
