What was the total supply of the Drift Protocol?

Excuse me, could you please clarify for me the total supply of the Drift Protocol? I understand that this information is crucial for investors to assess the potential scarcity and value of the tokens. Could you elaborate on whether the supply is fixed or subject to change over time, and if there are any specific mechanisms in place to manage the supply and ensure stability? Additionally, is there any publicly available data or documentation that outlines the total supply and any related details? Thank you for your time and assistance in answering my query.
