Incorrect usage of "call" instead of "read" in Reading Data from a Smart Contract Example

[abregand]

Example incorrectly uses the call method instead of read to fetch data from the contract. Link to docs

Here is the incorrect snippet from the example:

const result = await contract.call('balanceOf', args);
const balance = U256.fromBytes(result);

Correct Approach:

const result = await contract.read('balanceOf', args);
const balance = U256.fromBytes(result.value);
