no team notifications on Huawei P20Pro

Hi,
I've installed team and it has connected and I send and recieve messages on my huawei phone. However, when the application is not open, i get no notifications for incoming messages - neither sounds, nor icon changes or any other notifications. I've made sure that the individual notification settings permit notifications under all circumstances, still no luck.

what am i doing wrong?

I'm running android 9 with emui 9.1.0.361
