I'm helping a client who has just hired a developer to make an app for them. The client has an organizational Apple Developer account, and I need to set up their account so that the developer can publish to testflight and the app store.
I've already added the developer to the team in Appstore Connect, but the option to publish as part of the client's team still doesn't show up in their XCode. I experimented with an alt account that I have and encountered the same problem when I added myself to the team. Do I need to share a certificate with the developer, or is it something else? Can someone walk me the steps, or point me in the right direction? I've done a bit of app development myself, but only as an individual, and I'm not very knowledgeable on certs and signing.
