I was added as a developer via Business Connect. Do I still need a developer membership?

Hello,

I am working on a new App for my company that will be available for iOS and Android. I develop it in Visual Studio using .NET MAUI. I can deploy my development version of the App on an Android device without issues, but when I try to deploy to an iPhone, a dialog wants my Apple credentials.

I was invited as a developer in Business Connect by the product manager. The account that invited me is already used for publishing several Apps the company made in the past. I log in with my new Apple developer account, confirmed all legal notices, but when I try to connect to the iPhone from Visual Studio, I get the following error.

The Apple account is used for publishing Apps and I was invited as a developer. Do I need to enroll to the Apple Developer Program with my new account just to test the software on my iPhone?
