This my not be the ideal solution, but I would maybe try using hotkeys on your desktop - Alt+Esc will cycle through windows and bring then to the front which may help?
you also have Alt+Tab though im not sure how well UiPath will interact with that.
Can you get good selectors for the terminal window itself? if you open up UiExplorer and then get the terminal window open, and spy it, can you then use that to attach or click to bring it to the front?
