Expiration date picker: selecting a month doesn’t navigate to that month (requires manual “Back to date selection”)

[Yulkiii]

Is your feature request related to a problem? Please describe.

When creating a Personal Access Token, the expiration date picker has a month selection view. After selecting a month, the UI does not automatically navigate to the corresponding month’s calendar (day selection view). Users must manually click “Back to date selection” to return to the calendar view.

This breaks the expected flow (month selection → day selection) and feels unintuitive, because the “Back” action becomes a required step to continue.

Steps to reproduce

1. Open Coze Studio and go to Personal Access Token creation.
2. Click Add new Personal Access Token.
3. In Expiration time, choose Custom.
4. Open the date picker, switch to the month selection view (year/month list).
5. Select any month (e.g., May 2029).

Actual behavior

• The UI stays on the month selection view after clicking a month.
• User must manually click “Back to date selection” to return to the calendar/day view, then pick a specific date.

Expected behavior

• After selecting a month, the date picker should automatically switch to the calendar/day view and display the selected month, so the user can immediately pick a day.

Describe the solution you'd like

• Auto-navigate to the chosen month after a month is clicked:

  • Month selected → automatically return to calendar/day picker → show the selected month.

• (Optional) Keep a clear header/breadcrumb like “2029 / May” to confirm current context.

Describe alternatives you've considered

1. Add a “Confirm/Next” button in the month selection view (instead of requiring “Back to date selection”).
2. Keep the month selection view, but allow selecting a month to auto-close the month list and return to the day view immediately.
3. Make the header clickable to toggle between month view and day view (common date picker pattern).

Additional context

• Occurs in the “Add new Personal Access Token” modal’s expiration date picker.
• Screenshot attached (month selection view shows “Back to date selection”; selecting a month does not navigate automatically).
