Is there an easy way to add performance tracking not just exception tracking to the Sentry integration. Note we don't have access to the Sentry init function (when the app is booted) and can not find anywhere where it says how it is initialised. Sentry reports errors, but do we need to configure opentelemetry ourslves for performance tracing? Without being able to see init function, coding blind.... https://docs.sentry.io/platforms/javascript/guides/node/opentelemetry/custom-setup/
