I want to create a form from the Human-Readable ABI using the json file truffle creates. so the idea is to get the string Human-Readable ABI and then use regex to cut out and use the different parts to create my form. But using ethers.utils.FormatTypes.full does not return a string like the documentation suggest.

Here is my code:

 const iface = await new ethers.utils.Interface(Bank.abi);
 iface.format(ethers.utils.FormatTypes.full);

expected output:

[
 'function deposit() public payable',
 'function withdraw(uint256 _amount)',
 'function checkAssets() public view returns(uint256)'
];

actual output: According to the documentation: Converting Between Formats

ethers.utils.FormatTypes.full ⇒ string. This is a full human-readable string, including all parameter names, any optional modifiers (e.g. indexed, public, etc) and white-space to aid in human readability.

But instead, it returns an object. Can anyone please assist?
