[2020] Buying from Epic Store....

Hi there. I 'd like to ask you guys a little doubt of mine. I have Div2 Ultimate already and I'd like to get the new Expansion. But I have a discount coupon @ Epic Store (I don't like them, but....) and the game would became a little cheaper for me. If i buy the Warlords of New York Edition (Div2 + Expansion) will I be able to use it with my Ubi account? I mean, Will it activate only the expansion with it or will get me in trouble and make me create a new ubi account?

Thanks in advance!
