Developing Games on Unity3D For Distribution on Galaxy seller portal

Hi There
I Want to implement a user rating request to my game Battle of Galaxy (Content ID : 000005535550)
which I have made in unity_2019.4.9f1_and Built for android ; currently live on Galaxy Store.

Your web page has instruction for AndroidManifest.xml file modifications for Rating Request Board implementation But I could find nothing on your site neither on unity site for User Request board implementation.

Will it be Automatically implemented if I submit through Unities Distribution Portal?
Can you Please Guide me on how to implement this on Unity engine and Then build it ?

Thanking You
H.Moshtagh

I was told
Currently this feature is not supported in Unity by default, but it may be possible to get it to work by writing some Android code and importing it into Unity.
