My app was rejected by the reason "Misleading"

I developing the application for the government. So I upload as Unlisted app. But my app was rejected with this reason.

Your app or its metadata appears to contain potentially misleading content. Specifically, your app includes content that resembles “....My Government....." without the necessary authorization.

Next Steps

Please demonstrate your relationship with any third-party brand owners represented in your app.

So what is the content I must write into this documents or any ways to solve this problems?

Thanks a lot
