WEB Alert wait until alert appears

Hi team.

Does Web Alert step guide wait time according to the Browser Delay parameter?

We manage a web site that requires a search for data at the server site and depending on the results, it displays an Alert if no records are found and takes some time.
When using the Legacy Web Alert message capture, it sometimes misses the message and we have inserted Row Delays and still have issues when message is delayed.

As we are also migrating to the new GUI platform, need some further explanation to this Note in the documentation: NOTE: All alert handling steps should be added in a workflow before the step which triggers an alert. e.g. If a mouse action step opens an alert on page, alert step must be added before that mouse action in a workflow to make it work.

Thanks
