Without the event builder methods I am unsure how I am supposed to manually capture events using captureEvent.

As per #4887 (comment) - we are closing this PR. We want to avoid increasing API surface whenever possible - and the top level eventbuilder exports were undocumented APIs used only for the @sentry/electron SDK. Thanks for reaching out!
