Custom app with Public and Private Distribution

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!

Hi there Hoang. Were you able to figure out if this is possible? :)
