I using Odoo14,

I have users on my company, there is a cashier and there is an accountant,

I want  an accountant can Confirm and POST customer invoice.

And I want  a cashier don't have access to it (can't confirm and post invoice), but he can do Register Payment, but in the other hand, I also don't want accountant can do Register Payment.

the conclution:

• Accountant can do Confirm and POST Invoice, but can't do Register Payment
• Cashier can do Register Payment, but can't do Confirm and POST invoice

am trying to make security group like this:

and trying to inherit account.view_move_form view like this:

the Cashier and and Accountant still look same.

So how to inherit button on a form and  updates  it   groups ?

Thanks,
