Crashes coming form sentry.native under the Android SDK should be reported as:
sentry.native.android.dotnet
Currently, it's reported as sentry.native.android, which is the same as standalone Android apps.
On the Unity SDK, we override it at compile time, and here we don't recompile the SDK so not sure if it can be easily done:
