Hi @ECCBV ,
Which endpoint do you use? The following one will list for you all groups:
List groups
/api/2.1/accounts/{account_id}/scim/v2/Groups

Now, if you want to list a members of the group you need to use following endpoint and provide group_id parameter:
Get group details
/api/2.1/accounts/{account_id}/scim/v2/Groups/{id}
