How to use movement sensor with Go2Sleep

I use Sleep as Android, few days ago starting to use Go2Sleep ring.
Go2Sleep ring can read HR and SpO2 data to Apps, but can’t read movement.

I want to get movement data for other alternate devices(ex. SONY smartwatch, mi band) or direct to smartphone sensors.

But I don’t know how I do it.
So please tell me how to do it.

Sorry, simple English.
