Deploying ERC20 contracts for minting

I am implementing this - - the contract deploys but I do not see the minting option.

I saw _mint is coded but it does not appear on my Remix screen after deployment. Do I need to change something? I entered the addresses for the actual imports as follows -

import ".deps/github/OpenZeppelin/openzeppelin-contracts/contracts/token/ERC20/IERC20.sol"; 
import ".deps/github/OpenZeppelin/openzeppelin-contracts/contracts/token/ERC20/extensions/IERC20Metadata.sol";
import ".deps/github/OpenZeppelin/openzeppelin-contracts/contracts/utils/Context.sol";
