Expo managed workflow support for react-native-get-random-values is only avaiable in SDK 39 and higher.

Exactly like the title says. This is what I am getting when just importing react-native-get-random-values.

Correct me if I am wrong, but that version doesn't yet exist?

Exactly: Expo SDK will be released within the next few weeks and only then react-native-get-random-values will start working in expo managed workflows.

See #13 for details and references.
