@harshavardhinip This one is tricky. I have found that the best way is to use a small C# script to hide the Chrome (or Edge) window when the initial page is created.

Caveats;

1. This will hide the window that the page is on. This may include any other tabs open in the same window. You cannot hide only one tab (to my knowledge anyway).
2. This will not hide any pop-up or dialogs from the window in question. You could in-theory hide them on creation if you can interrogate them as well, but hopefully your automations to handle any pop-ups are brief and render this unnecessary.
3. The hidden window's pages will match just as if they were visible. That means that if you have a hidden version of an application and a user opens their own visible copy, its pages would match against the hidden one and would need to be handled the same way (with cloning most likely).

Let me know if you have any questions.
