Hi,

Please refer to the code below:

<record id="custom_model" model="ir.actions.act_window">
    <field name="name">Custom Model</field>
    <field name="res_model">custom.model</field>
    <field name="view_mode">kanban,list,form,activity,pivot,graph,cohort</field>
    <field name="domain"></field>
    <field name="context">{'default_custom_context_field': True}</field>
    <field name="help" type="html">
       
    </field>
</record>

Invisible field:

<field name="custom_field" invisible="context.get('default_custom_context_field')"/>

Hope it helps.
