How to use the trezor-connect.init function in trezor-connect

private async connectInit (args: TrezorConnectArgs): Promise {
    // Collect connect events that happen during init, but don't handle them
    // until after init has resolved. This awkward sequence is needed because we
    // need TrezorConnect to be fully operational before we're able to process
    // the events.
    let connectEvents = []
    let connectHandler = (event: any) => {
      if (event.type === 'device-connect') {
        connectEvents.push(event)
      }
    }
    TrezorConnect.on(DEVICE_EVENT, connectHandler)

    // TODO: using this in electron will needs some more scaffolding:
    // https://github.com/szymonlesisz/trezor-connect-electron-boilerplate/blob/master/src/electron.js
    await TrezorConnect.init({
      ...args,
      popup: POPUP,
      lazyLoad: false
    })

    TrezorConnect.off(DEVICE_EVENT, connectHandler)

    for (const connectEvent of connectEvents)
      this.handleConnectTrezor(connectEvent)

    TrezorConnect.on(DEVICE_EVENT, (event: any) => {
      if (event.type === 'device-connect') {
        this.handleConnectTrezor(event)
      } else if (event.type === 'device-changed') {
        this.handleChangeTrezor(event)
      } else if (event.type === 'device-disconnect') {
