You are not in the Provision Managers group" Error Despite Proper Setup

We are encountering an issue when attempting to perform user management actions via the 1Password CLI. Even after enabling provisioning and creating a "Provisioning Manager" group with the "Provision People" permission (as per the documentation), and adding our dedicated provisioning account to this group, the following error persists:

[ERROR] 2025/04/29 06:10:15 You are not in the Provision Managers group.

Could you please assist in identifying what might be missing? We would also appreciate a step-by-step guide to properly configure and use the user management CLI actions as outlined in your documentation here:

Thank you
