Mi 4 Fitness Tracker Whatsapp notification does not arrive?

Hi. I bought the mi 4 band, the fitness tracker. It is said that it should be possible to display Whatsapp messages. I can only receive sms and incoming calls. Can someone help me? Oh yes, I have the huawei p 20, maybe that's still important. Thank you, sorry, I don't know my way around well. LG Bara

You go to the MiFit app.
Then on "Profile"
Then you click on the menu item of the bracelet
To the point "App notifications
Since activate that.
Then on "Manage Apps"
And there you choose all apps that can send notifications to the band.
