Ok simply by having the EA app running and then locating the game files through steam and then just launching the game through the game .exe it works with the EA app without issues . So this lead me to one conclusion that it is possible to launch the game through the EA app even if I purchased it through steam.
This is tested with KnockOut City which I purchased through steam .
All I understand is that Ea and Origin software both operate in the same way. Also in the future origin will be removed and the EA app is going to be the software for the future.
So it's either not supported yet because the EA app is beta which can be a reasonable reason or it's something developers did miss and it needs to be fixed.
