Play Sims 4 only through Origin?

When I was just looking at my installed apps, I saw that the Sims 4 with a few extensions occupied a little over 15 GB of memory.

I recently bought a workstation and installed Origin out of interest to see how the Sims 4 runs on it. I noticed that the Sims 4 was not installed on this computer, but I was still able to play the game with extensions using Origin.

Could I just play the Sims 4 on my laptop via Origin, or does the game have to stay installed on my computer?

As far as I know, it should only work in Origin as long as it's installed there.

Best wishes and stay healthy.
