Pairing Ikea sensor

I have installed an Ikea sensor to an Ikea light bulb connected to Phillps hue bridge. It seems to be working in the app and the sensor turn on and off the light with the default 3 min timer.

How do I add the sensor to HA? I only see the light I have added to the sensor, but I don’t see the ikea sensor with any reference of binary_sensor.tradfri_motion_sensor.
