How to use the gatsby-cli/lib/reporter.pendingActivity function in gatsby-cli

module.exports = async (program: IProgram) => {
  initTracer(program.openTracingConfigFile)
  report.pendingActivity({ id: `webpack-develop` })
  telemetry.trackCli(`DEVELOP_START`)
  telemetry.startBackgroundUpdate()

  const port =
    typeof program.port === `string` ? parseInt(program.port, 10) : program.port

  // In order to enable custom ssl, --cert-file --key-file and -https flags must all be
  // used together
  if ((program[`cert-file`] || program[`key-file`]) && !program.https) {
    report.panic(
      `for custom ssl --https, --cert-file, and --key-file must be used together`
    )
  }

  try {
    program.port = await detectPortInUseAndPrompt(port)
