How to use the react sdk to send all sentry events to a private server, which then forwards them to the proper sentry dsn?

Ideally it would be as simple as setting the DSN in Sentry.init to the private server's address, but obviously this isn't accepted by the sdk because it extracts information like public key from the provided DSN. Does anyone know a lightweight way of setting this up?
