Add 721 via button similar to ERC20 API

Feature Requests
1

There is a new API to add tokens via a function, so that sites can have a button to show “add to metamask”

Is there a similar feature for adding ERC-721s?

I cannot find this in the documentation. Only for ERC20s


const tokenAddress = '0xd00981105e61274c8a5cd5a88fe7e037d935b513';
const tokenSymbol = 'TUT';
const tokenDecimals = 18;
const tokenImage = 'http://placekitten.com/200/300';

try {
  // wasAdded is a boolean. Like any RPC method, an error may be thrown.
  const wasAdded = await ethereum.request({
    method: 'wallet_watchAsset',
    params: {
      type: 'ERC20', // Initially only supports ERC20, but eventually more!
      options: {
        address: tokenAddress, // The address that the token is at.
        symbol: tokenSymbol, // A ticker symbol or shorthand, up to 5 chars.
        decimals: tokenDecimals, // The number of decimals in the token
        image: tokenImage, // A string url of the token logo
      },
    },
  });

  if (wasAdded) {
    console.log('Thanks for your interest!');
  } else {
    console.log('Your loss!');
  }
} catch (error) {
  console.log(error);
}

If not…why not? We should have this 100%.

Willing to help work on the code as well.
