google reject apps use sms permissions

Question

I want to publish an SMS forwarder app in the Google Play Store but rejected several times. google permitted use for SMS permission documented in this link, are the following:

• Default SMS handler

  Example of permitted use: A user relies on a default SMS app to receive and send SMS messages.

or

• Default Assistant handler

  Example of permitted use: A user uses this app to receive, translate, and reply to SMS conversations in real-time in someone else’s native language.

I published my app as the default SMS handler but was rejected and I think, permitted use (based on Google documentation) must be Default Assistant handler. but I didn't find anything about how to be a default assistant handler in Android developer documentation.

What should I do?

Thanks.
