Hello @jva, the topic you replied to is about the deCONZ gateway, so I moved your post to the Philips Hue topic about the IKEA smart controls.
Third party smart controls are not visible in the app when connected to a Hue bridge, so you cannot configure anything. There is no wizard.
What you could try is removing the battery for 10 seconds and after reinserting it check if the left/right buttons work. If that does not work, there is unfortunately not much we can do about that. Maybe someone else here has a solution for the left/right buttons not working.
