How to use the @walletconnect/utils.removeHexPrefix function in @walletconnect/utils

export async function verifyHmac (
  payload: IEncryptionPayload,
  key: ArrayBuffer
): Promise {
  const cipherText: ArrayBuffer = convertHexToArrayBuffer(payload.data)
  const iv: ArrayBuffer = convertHexToArrayBuffer(payload.iv)
  const hmac: ArrayBuffer = convertHexToArrayBuffer(payload.hmac)
  const hmacHex: string = convertArrayBufferToHex(hmac, true)

  const unsigned: ArrayBuffer = concatArrayBuffers(cipherText, iv)
  const chmac: ArrayBuffer = await createHmac(unsigned, key)
  const chmacHex: string = convertArrayBufferToHex(chmac, true)

  if (removeHexPrefix(hmacHex) === removeHexPrefix(chmacHex)) {
    return true
  }

  return false
}
