It has been removed many versions ago. You can use the UI, StreamDeck or WebSockets to manually trigger rewards.
Ah fair one, yeah I don't update on every release so I must have missed that. No worries - I can set something else up using WebSockets. Sadly I can't afford a StreamDeck right now but that'll be a future investment. Keep up the good work buddy, my friends and I love this software, we've had a lot of fun with it.
