I'll try to write a post on the same. Usually when someone is creating a token, they define the tokenomics on how they are going to define the supply. If the token is for Tribe, there is a setting available that defines the tokenomics. The owner usually has a button to mind how much ever token they want. Some projects mint the tokens when they create it and supply them one by one and some projects let the smart contract mint the tokens whenever it is required.
