/legacycalendar not working

Steps to reproduce:

1. Open Niagara Search.

2. Enter /legacycalendar and execute the command.

3. Return to the home screen.

4. Tap the date.

5. Niagara's Agenda still opens instead of the Google Calendar app.

The command visibly toggles on/off, but the behavior does not change.

Expected behavior: With /legacycalendar enabled, tapping the date should open the device's calendar app.

Actual behavior: Tapping the date continues to open Niagara's Agenda.

Only Google Calendar is installed as the calendar app.
