NativeModule is null in Expo / but works in Native CLI

NodeModule-is-Null

I’m working on a react native app and wanted to import the Module “@native-react-community/geolocation”. I followed the installation on the git page. I launched the App with the Expo CLI and get the Error “NativeModule.RNCGeolocation is null”. I tried every fix in the Error Message, nothing works. When i launch the App with the Native CLI, everything works.

Is that a problem with Expo or am i doing something wrong?
Grateful for any help
Cheers
