Cannot create a new Group in alfresco using the REST API (/groups) POST - rest

Question

Greetings to the community! I am trying to create a new user group on alfresco using the REST API following this guide https://api-explorer.alfresco.com/api-explorer/#!/groups/createGroup. I am using Postman to make the REST calls. I have successfully so far managed to create new users using the (/people) (POST) method like shown below:
POST: http://localhost:8080/alfresco/s/api/people?alf_ticket=TICKET_<<my_alf_ticket>>
and the following JSON in the Body:
{
"userId": "user",
"password": "pass",
"userName": "user",
"firstName": "user",
"lastName": "user",
"email": "user#user.com"
}
Unfortunately, when I am similarly trying to create a new group like following
POST: http://localhost:8080/alfresco/s/api/groups?alf_ticket=TICKET<<my_alf_ticket>>
and in the body section
{
"authorityType": "GROUP",
"shortName": "GROUP1",
"fullName": "GROUP_GROUP1",
"displayName": "GROUP_GROUP1"
}
I am facing the following error
Any help would be greatly appreciated :)

This is old api:
1) POST http://localhost:8080/alfresco/s/api/rootgroups/{shortName} to create group
2) POST http://localhost:8080/alfresco/s/api/groups/{shortName}/children/{fullAuthorityName} Adds a group or user to a group.
For new api you should use:
POST http://localhost:8080/alfresco/api/-default-/public/alfresco/versions/1/groups
CURL
curl -X POST --header 'Content-Type: application/json' --header 'Accept: application/json' --header 'Authorization: Basic YWRtaW46YWRtaW4=' -d '{
"id": "TEST_GROUP_ID",
"displayName": "Group for tests"
}' 'https://api-explorer.alfresco.com/alfresco/api/-default-/public/alfresco/versions/1/groups'
Response
{
"entry": {
"isRoot": true,
"displayName": "Group for tests",
"id": "GROUP_TEST_GROUP_ID"
}
}
