We have a requirement in our project to embed an external web application into the Pega portal. We have several links on a page[ section/harness] clicking which will open different pages of the external application in the same Harness. I have gone through the PDN articles regarding embedding external web component but it doesn't give the correct way of configuring the same. I am using Pega PRPC v 8.3.3. What I would like to understand is where I can provide the link (URL) to the web application and how that can be integrated to our Pega application.
Also want to to understand how this works at a high level as I am not sure I fully understand the working of the same internally. Appreciate any help in this regards.
