Append new Permission using Management API

Is there a way to append a new Permission to an already existing API Permissions through Management API?
I followed the following example Add API Permissions but it removes existing permissions and only adds the new one sent in the request.

Hi @hadeel,

It looks like the permissions follow a similar schema as user data where

The properties of the new object will replace the old ones.

I tested it and can confirm this behavior. In order to preserve the existing permissions you will need to add them the patch request.
