Set up Amazon Fire Tv without remote control?

I have an Amazon fire tv stick here, but unfortunately no remote control for it. Since the stick is not yet connected to my WLAN, I can't control it via the app. Hdmi Cec does not work on my TV (LG) somehow, if I activate SimpLink, I still can't control the stick with the remote control. I have an Xbox one S with HDMI in here. Vlt someone knows it and can help me further. Otherwise I ask for further solutions

Take the Fire app.

Ah, sorry, had only read the question. Can't it really work without the FB?

The stick must be connected to the WLAN

Nope unfortunateley not
