|
|
description: >
|
|
This module can be used to create a new resource group in DECORT cloud platform, modify its
|
|
characteristics, and delete it.
|
|
version_added: "2.2"
|
|
author:
|
|
- Sergey Shubin <sergey.shubin@digitalenergy.online>

|
the DECORT cloud controller on which this JWT will be used.'
