How to use the frida-fs.unlinkSync function in frida-fs

console.warn(`unable to open ${filename} (${e.message})`)
        continue
      }

      await new Promise((resolve, reject) =>
        stream
          .on('data', chunk => {
            Memory.writeByteArray(buf, chunk)
            libarchive.writeData(ar, buf, chunk.byteLength)
          })
          .on('end', resolve)
          .on('error', reject))

      // delete decrypted file
      if (relative in lookup)
        fs.unlinkSync(filename)

      libarchive.writeFinishEntry(ar)
      libarchive.entryFree(entry)
    }

    libarchive.writeFinish(ar)
    console.log('done', pkg)
    return transfer(pkg)
  },
  skipPkdValidationFor(pid) {

recv('flush', () => { }).wait()
        sent += chunk.byteLength
        console.log(`downloaded ${format(sent)} of ${format(size)}, ${(sent * 100 / size).toFixed(2)}%`)
      })
      .on('end', resolve)
      .on('error', reject))

  send({
    subject,
    event: 'end',
    session,
  })

  console.log('transfer complete')
  fs.unlinkSync(filename)
