Why doesn't Huawei mate50 have a walking switch in the settings?

Huawei mate50 has no walking switch in the settings because it is in "health" or "sports health". In "Health" or "Sports Health", you can find options such as "Pedometer" or "Steps". When you enter the pedometer or step count page, you can see the relevant switches, and you can turn the pedometer function on or off.
