Hello, today I find code that using "ir.actions.todo".
<record id="base.open_menu" model="ir.actions.todo">
<field name="action_id" ref="action_open_website"/>
<field name="state">open</field>
</record>
but "ir.actions.todo" was not in the odoo development document actions.
https://www.odoo.com/documentation/13.0/reference/actions.html
Currently, I don't know what "ir.actions.todo" do and what is field "state" is.
I want to know where can I find a document about this.
Waiting for your help.
