To clarify: I can launch games from steam that don't have a launcher. I open steam and get out of big picture mode.There is a plus sign on the bottom left of the steam page. I click that then click add a non steam game and it starts searching and never stops or finds my other programs. I usually can add programs when they pop up after searching.Now it just searches and doesn't find anything. I have used this method before to launch ea origin and ubisoft connect, then launch my game from origin and ubi connect.I do it this way so I can use my steam controller.
