As another user said you need to install the “torrentio” addon which gives you access to pretty much all the torrents, it has it’s own website. This can be done on Desktop or mobile(Android)
On TV you first have to configure Stremio on a phone or PC with a Stremio account(free) and then sync your addons on Stremio TV with the same account.
A bit tricky and confusing, but it is easy, you can find more compressible tutorials on YouTube
