I have an app, which currently design for my company, my app use Custom distribution with Apple Business Manager. Users can not manually create accounts. But I want to create this feature in the next version, make the app can use with a wider target. Can I make it public? If my app can not public because of my current distributions, can I create a new one for the public?

Hi everyone! I make an app and publish it to the app store, I choose the Custom app, private distribution. My app can be installed by using a redeem code via Apple Bussiness Manager. However, I want to develop my app for a wider range of users, they may be a small team, not only a company. What solutions for me? I found that I can not change my app from private to public. If I want it for public publishing, I need to create a new one. However, If I create a new one, the content is the same ( i add more function about sign in as a guest, register for it to satisfy wider user can use it like apple policy ), whether my app can be approved or rejected? Thank you for reading my question! I hope the help from you!
