We are with Odoo v15 .sh.

While doing the payroll, we want to have an approval process to confirm the payroll batch prepared by an employee, the payroll should be approved by the company manager, HR manager, and the CEO.

So when the payroll batch is prepared there should be a notification to the company manager, HR manager, and the CEO for approval, and after they approve they should be able to confirm the payroll batch. Hence by studio how to do the 3 user approvals with the notification trigger?

Thank you
