Apple Store rejection

Hello dear community,
I need your help. I am currently in the process of publishing the app in the Apple Store for a customer. I’ve tried a lot to do this, but Apple keeps refusing to publish it. The reason is that the company-specific application violates the guidelines of the Apple Store and refers to the Apple Business Manager. However, this does not match with the customer’s requirements. I have now installed a public section, but still no chance. Do you have any ideas, tips or a workaround with which a publication is possible?
I am very happy about your help and support,
best regards
