Uploading a Whitealabel app to the App Store

I am whitelabeling the Rocket.Chat app for use with a small but growing group of people. I want to make it as easy as possible for them to download and use the app as many of them are not very tech savvy. When going to upload the app, the review process flagged it as a violation of guideline 4.3 - Spam. My question is: 1) Is there another way that would be better to distribute my app? 2) Is there a way I can change my app or my listing so as not to violate 4.3 as spam is absolutely not my intension.

Thank you for your help!
