First thing you need is to get your Apple App Store Developer account for your organization. They have to be organization accounts in order to publish with our system.
Once you have your account ready, you’ll need to add firstname.lastname@example.org as a developer to your team (ideally with admin access).
Once you do that, we build your app for App Store again, with our permissions to build on behalf of your team. Once that’s done, you or someone from your team can publish to both stores under your account. OR if you’d like, we also provide one time addon services for publishing.
