[Python] How to display the "New" button in calendar view like in tree or kanban views?

I’m working with Odoo 17 and I’ve created a calendar view for a custom model. In tree and kanban views, the standard "New" button appears at the top left, allowing users to create a new record.

However, in the calendar view, this "New" button does not appear. I have already set create="true" in my calendar view definition, and quick creation is working when clicking on the calendar itself.

But I would like to also have the standard "New" button (like in other views) visible in the calendar view’s header. Is there a way to enable or force this button to appear in the calendar view?

Here is a snippet from my view:

<calendar string="Appointments"
date_start="date"
date_stop="date_to"
mode="week"
color="state"
create="true"
event_open_popup="true"
quick_create="true"
quick_create_view_id="%(view_dental_appointment_quick_create)d">
<field name="name"/>
<field name="patient_id"/>
<field name="physician_id"/>
<field name="department_id"/>
<field name="duration_id"/>
<field name="phone"/>
<field name="cabin_id"/>
<field name="state"/>
</calendar>
