Hi there,  
So I have been using Selenium Library for web automation using Robot Framework.  
The pop up authentication is not working as how it works in Selenium Java (another framework)  
example: [https://username:password@testing.com](https://username:password@testing.com) - this doesnt work in robot framework.

therefore I use browser library. But it uses chromium.  
hence, shifting back to selenium library is not possible.

could someone help me and advise on using multiple librabies in one test ?
