   - `globalHubMode` used to only be a param on `Sentry.init`. To make it easier to be used in e.g. Desktop environments, we now additionally added it as an option on SentryOptions that can also be set via `sentry.properties`.
   - If both the param on `Sentry.init` and the option are set, the option will win. By default the option is set to `null` meaning whatever is passed to `Sentry.init` takes effect.
