German Corona Warning APP


On my Chinese MI 11 Ultra (MIUI 12.5, Playstore installed, Google apps working fine) I can not use the german Corona APP because after installing and starting the app it says that the necessary Google API is missing. https://developers.google.com/android/exposure-notifications/exposure-notifications-api
Is there anythingn I co do ?
Thank you
How about installing .eu Rom?
