What is the max supply STX?

Could you please clarify for me, what exactly is the maximum supply of STX? I'm trying to understand the scarcity potential and long-term sustainability of this particular cryptocurrency. Is there a finite number of STX coins that will ever be available, or is there a potential for further issuance? Additionally, how does the maximum supply factor into the overall economics and value proposition of STX? Thank you for your assistance in helping me better grasp this aspect of the cryptocurrency world.
