How do I set up True wireless stereo on Beosound Explore without using the Bang & Olufsen app?

To set up stereo pairing manually, first press and hold the Bluetooth button on the first speaker for 5 seconds until the light indicator flashes white. Then perform the same operation on the second Beosound Explore. After 10 seconds, both speakers will make sound prompt to inform that they are connected, and the light indicator will change from flashing to solid white.
