ROG 3 Cannot connect to Kunai 3 gamepad by Bluetooth

Please tell us some basic information before asking for help:

- Firmware Version: lastest
- Rooted or not: no
- Frequency of Occurrence:
- APP Name & APP Version (If your issue relates to the app):
In addition to information above, please also provide as much details as you can, e.g., using scenario, what troubleshooting you've already done, screenshot, etc.
========================================
I've just bought the kunai 3 gamepad. According to the user guide, it said the kunai 3 can be connected to my Rog 3 by turning to the Bluetooth mode, and clicking one time the home botton and then click it one more time for 3-5 seconds until the white light occurs. The breathing light should be blue and lights for a few times.
Yet, I've followed all the steps. The breathing light was green and when I click it for 3-5 seconds, it seems to reboot or shut down itself by showing no light. The whole process continues as I've tried it few times.
PLEASE PROVIDE THE SOLUTION FOR BLUETOOTH CONNECTION. THANK YOU.
