How to use the @polkadot/extrinsics/codec/encode/prefixes.none function in @polkadot/extrinsics

export default function encodeType (type: Param$Type, value: any, version: EncodingVersions): Uint8Array {
  try {
    switch (type) {
      case 'AccountId':
        return u8aConcat(
          version === 'poc-1'
            ? addrPrefixes.none
            : addrPrefixes.publicKey,
          addressDecode(value)
        );

      case 'Balance':
        return bnToU8a(value, sizes.Balance.get(version) || defaultSizes.Balance, true);

      case 'BlockNumber':
      case 'Gas':
      case 'SessionKey':
      case 'u64':
        return bnToU8a(value, 64, true);

      case 'bool':
        return bnToU8a(value ? 1 : 0, 8, true);
