Download app on Samsung TV tq65q7faauxxc?

Hello everyone,

I bought a Samsung TV tq65q7faauxxc However, I noticed that there is no real store. Not a real one because via search function I could download one app. But there aren't everyday life apps like Spotify for instance. Is there a way to download app via Google Play or another store?

I saw that from my phone I could cast my Spotify app, so listen to music on the TV.

Thank you for your help !
