Maybe you can have a look at the documentation: [ERC 20 - OpenZeppelin Docs](https://docs.openzeppelin.com/contracts/4.x/api/token/erc20#IERC20-approve-address-uint256-)

I think you will see:

- Approve
- Decrease allowance
- Increase allowance
- Transferfrom
- Allowance

But for other functions, I am not sure where do you find them, so you need to look at the contract that contains these functions to see.
