Odoo Version: Odoo 16.0 Online

I would like to remove the dynamic button that displays at the top of all e-mails in odoo ( View Quote, View Invoice, View Purchase Order, Accept & Sign Quote etc...etc..) 

I believe this is hardcoded in the view Mail: mail notification layout template, please correct me if I am wrong.

I also believe that the fix is
1. Create a new view
2. Inherit the existing view
3. ????Magic X-Path code to "replace" this area

Can someone please provide the exact code I would use to remove this header?
