I need to create and apply custom filter on button press. I have created button on view which leads to calendar, but also I need to pass and apply my custom search filter to that calendar view.

<record id="view_task_form2_meetings" model="ir.ui.view">
    <field name="name">project.task.form</field>
    <field name="model">project.task</field>
    <field name="inherit_id" ref="project.view_task_form2"/>
    <field eval="2" name="priority"/>
    <field name="arch" type="xml">
      <xpath expr=".//button" position="before">
        <button class="oe_inline oe_stat_button" type="action"
        icon="fa-calendar"
        name="project_task_meetings.task_meeting_event"
        context="{'search_default_task_id': [1],
                                  'search_default_task_id': 1}">
          <field string="Meetings" name="task_meeting_count" widget="statinfo"/>
        </button>
      </xpath>
    </field>
   </record>

I expected context to do the trick but it doesn't. Then I was told that action in name should work. There it is:

<record id="task_meeting_event" model="ir.actions.act_window">
        <field name="name">Meetings</field>
        <field name="res_model">calendar.event</field>
        <field name="view_mode">calendar,tree,form</field>
        <field name="view_id" ref="calendar.view_calendar_event_calendar"/>
        <field name="search_view_id" ref="calendar.view_calendar_event_search"/>
        <field name="context">{"search_default_task_id":1}</field>
    </record>

But still no success. May I have any help
