If you are inheriting ERC20.sol by Openzeppelin ([https://github.com/OpenZeppelin/openzeppelin-contracts/blob/master/contracts/token/ERC20/ERC20.sol](https://github.com/OpenZeppelin/openzeppelin-contracts/blob/master/contracts/token/ERC20/ERC20.sol))  
You only need to call [\_mint()](https://github.com/OpenZeppelin/openzeppelin-contracts/blob/master/contracts/token/ERC20/ERC20.sol#:~:text=function%20_mint(address%20account%2C%20uint256%20amount)%20internal%20virtual%20%7B) function inside your contract.

An example could b:

```auto
function mint(uint256 amount) external onlyOwner{
    super._mint(msg.sender, amount);
}

```

I didn't understand if you need a mint function or just set the supply after deployment

Sorry, I am not sure what do you mean. I think you mean you want to update the token address, right? Or something else?
