How to use the eth-sig-util.typedSignatureHash function in eth-sig-util

const result = await promisify<{ result: string, error: Error }>(
        this.web3.currentProvider, 'sendAsync'
      )({
        method: 'eth_signTypedData',
        params: [params, this.channel.account],
        from: this.channel.account
      });
      if (result.error)
        throw result.error;
      sign = result.result;
    } catch (err) {
      if (err.message && err.message.includes('User denied')) {
        throw err;
      }
      console.log('Error on signTypedData', err);
      const hash = typedSignatureHash(params);
      // ask for signing of the hash
      sign = await this.signMessage(hash);
    }
    //debug
    const recovered = recoverTypedSignature({ data: params, sig: sign  });
    console.log('signTypedData =', sign, recovered);

    proof.sign = sign;

    // return signed message
    if (proof.balance === this.channel.proof.balance) {
      this.setChannel(Object.assign(
        {},
        this.channel,
        { proof, next_proof: proof }
      ));

let returnData = {}
      returnData.signature = result.result

      // ensure that the signature matches
      const recoveredAddress = ethUtil.toChecksumAddress(ethSigUtil.recoverTypedSignature({
        data: typedData,
        sig: returnData.signature
      }))
      if (ethUtil.toChecksumAddress(recoveredAddress) !== from) {
        return reject(Error(
          `The returned signature '${returnData.signature}' originated from '${recoveredAddress}', not '${from}'.`
        ))
      }
      returnData.from = from

      returnData.messageHash = ethSigUtil.typedSignatureHash(typedData)
