How do I stop Bittorrent Web from launching at Startup>

I found an old post on the same issue with Bittorrent which advised to turn that off in Preferences. However, I don't see Preferences in Bitttorrent Web. In Login Items & Extensions, I see BitTorrent Web.app in the Open at Login tab in Login Items & Extensions, but I don't see a way to remove it there.

I think I just found the solution. At the bottom of Open at Login, there are a plus and a minus. Clicking the minus removes it. I'll see if it stays removed after I use it again.
