Macbook problems/ missing add ons

As I do not use my old laptop anymore I downloaded the ea app onto my new MacBook so I can play the sims 3, as I loaded the game it only showed that I had 3 expansion packs and all my other ones were missing. 

My packs were purchased years ago, I'm going to say around 2016/2017 when origin was a thing, I bought the packs with disks that I had to redeem a code with to download it. Obviously this was years ago so my disks with the codes are in the bin as when EA became a thing I didn't need to use them because all of my games were in the EA library. How do I get my games back into my library so that I can play them and don't need to use my old slow laptop that takes hours just to load the sims up.
