 * ```js
 * let arg1: CallArg = { Object: { Shared: {
 *   objectId: '5460cf92b5e3e7067aaace60d88324095fd22944',

 * let arg3: CallArg = { Object: { ImmOrOwned: {
 *   objectId: '4047d2e25211d87922b6650233bd0503a6734279',
 *   version: 1,
 *   digest: 'bCiANCht4O9MEUhuYjdRCqRPZjr2rJ8MfqNiwyhmRgA='

 *
 * For `Pure` arguments BCS is required. You must encode the values with BCS according
 * to the type required by the called function. Pure accepts only serialized values
