Application Publishing - Build issue

Hello

I am trying to publish my application built through Base44 but I am struggling with one element ''Unable to Add for Review The items below are required to start the review process: You must choose a build''

I have installed XCode but I am struggling with setting the application properly.

I have sent two emails to Apple Developer and been on the phone after two call back requests for nearly two hours and no response

Would anyone advise how to finalise this setup and publish the app?

Best wishes, Catalin
