Meizu 15 can't open Huawei Health. How to use the bracelet?

I bought a sports bracelet. When downloading Huawei Health APP, you need an OPPO account. What is OPPO? OPPO account is a personal account registered by OPPO mobile phone users, which can be used to log in to OPPO+, ColorOS community, OPPO members and other software.
