To use pako you must first convert your data from a hexadecimal string to a byte array. Here's one way to do this:

function decodeHex(hexString) { 
  let result = new Uint8Array(hexString.length / 2); 
  for (let i = 0; i < result.length; i++) {
    result[i] = parseInt(hexString.slice(2 * i, 2 * i + 2), 16); 
  } 
  return result; 
}
let json = pako.inflate(decodeHex("your string"), 
                        { to: 'string' });
let decoded = JSON.parse(json);
