How to use the @adonisjs/ace.Manifest function in @adonisjs/ace

public async handle (argv: string[]) {
    const { Kernel, handleError, Manifest, BaseCommand } = require('@adonisjs/ace')

    const manifest = new Manifest(this._ignitor.application.appRoot)

    kernel.useManifest(manifest)

     * Print help when no command is defined
     */
    if (!argv.length) {
      await kernel.handle() // This will load the commands from manifest
      this._printHelp(kernel)
      return
    }

    /**
     * Generate manifest when command is `generate:manifest`
     */
    if (argv[0] === 'generate:manifest') {
