Hi Kyle, welcome to Open Zeppelin.
You cannot increase the supply of a token unless it has a specific function that can do that. For example Mint! https://docs.openzeppelin.com/contracts/2.x/api/token/erc20#ERC20Mintable
Please take some time and follow some tutorials.
This is a great starter tutorial to get you into the thick of it. You don’t need to understand 100% of it, just be able to finish OpenZeppelin Upgrades: Step by Step Tutorial for Hardhat
Then take a look at Solidity learning resources
I know it’s a pain to take the time to teach yourself, but think of it as an investment. After you go through the tutorials you should be ready to build whatever smart contracts you want!
