as i said in packaged game steam pop up work fine, the only problem in VS, checked rama’s guide again, nothing new
here is link https://yadi.sk/d/l_yn3IwBgRVs2, if you can waste some time for me, would be great, because maybe noone yet tryed use steam functions and only just pop up, then our research additionaly to rama’s guide may save days digging around later for someone! 
i don’t even sure epic’s tryed use steam function from UE project, because in Engine they use Steam init of course and rebuilding whole engine seems very strange for me, but i got source code already and ready for such !@#$%^
