When attempting to integrate the Odoo interface into my Flutter application, running on http://localhost:8000/, using an iframe, a specific error message appears in the browser: 'Refused to frame 'http://localhost:8069/' because an ancestor violates the following Content Security Policy directive: 'frame-ancestors 'self'.' How can I resolve this issue, considering that the Flutter application runs on http://localhost:8000/ and Odoo on http://localhost:8069/?
