EA app on Steam Deck?

So, I am planning the transaction of a steam deck.  I want it for a few reasons, but a main reason is Sims Legacy.  I bought The 25th birthday bundle last week and I decided that I want to play it on the go.  So I want to buy Valve's portable PC known as the Steam Deck, but is the EA app available on the Steam Deck?  It is kinda where I bought the games.
