[BUG] Yeelight & Tasker: Only works if Yeelight app is open

I have created a task in Tasker, but it only works if I have the Yeelight app open. If it’s not, nothing happens.

Ideally, this would be fixed by Yeelight people directly.

Alternatively, who can tell me how to launch the app in tasker so it opens only in the background, so I can make a delay before initiating the main task?
