Native modules have to be compiled into the app. Installing the npm package only adds the JS side; your dev build was made before you added it, so the native part isn't in the binary.
Rebuild the dev client after adding any package with native code:
npx expo prebuild --clean # if you build locally
eas build --profile development -p ios
And it will never work in Expo Go, because Expo Go only contains the modules Expo ships.
