How to use the @kui-shell/plugin-bash-like.StdioChannelWebsocketSide function in @kui-shell/plugin-bash-like

const { wss } = await wssMain(N, server, port, cookie)

      debug('spawning subprocess')
      const child = spawn(process.argv[0], [mainPath, 'bash', 'websocket', 'stdio'], options)

      child.on('error', err => {
        console.error('error spawning subprocess', err)
        reject(err)
      })

      child.on('exit', code => {
        debug('subprocess exit', code)
      })

      const channel = new StdioChannelWebsocketSide(wss)
      await channel.init(child, process.env.KUI_HEARTBEAT_INTERVAL || 30000)

      channel.once('closed', () => {
        debug('channel closed')
      })

      channel.once('open', () => {
        debug('channel open')

        const proto = process.env.KUI_USE_HTTP === 'true' ? 'ws' : 'wss'
        resolve({
          type: 'object',
          cookie: {
            key: sessionKey,
            value: sessionToken,
            path: `/bash/${N}`
