I tried enabling air link I managed to get it running but when I connect my headset my games don’t appear in the library from when I downloaded them in the other store.
When you are running Airlink, you are accessing the Rift store instead of the Quest store.
Some games are only in one store (like Lone Echo 2 is only in the Rift store, Bogo is only in the Quest store).
Some games are in both stores, but are separate products so you have to buy them again. Beat Saber is like that, need to buy it twice to play natively on Quest and via Airlink.
Some games are "cross buy", which means when you buy on one store you get a free copy on the other store. Audica is like this. But they don't show up automatically, you need to go to the other store page and "buy" them again, but the price will be listed as Free.
