Hello, being in developer mode you can identify the button and then in the form view assign the groups you want, in this way you limit the visibility of the button to the people within the group. But you will not be able to add an Approvals, only define who approves.

note: if this is a group you created, you need to export it to get the id

Hi there, several Odoo modules have an approval mechanism already built-in, such as Expenses, Purchases, time-off etc.

However, to add an Approval to a model that doesn't already have it (such as Contacts) you would need either Studio, a 3rd party module, or a custom module.

There are some other alternatives, such as using Scheduled Activities, but they won't be as robust as one of the other options.
