How to do this in API2?

Good afternoon.
At the moment, the API for obtaining the hierarchy of contact groups via API v2 is not implemented.
There are 2 possible solutions:
1. We can implement this method in the shortest possible time - it will take 3 hours of revision.
2. We will implement this as an investment within a few months.
