Persistent "Cancel" or "Workflow Submitted" toast remains after manual trigger completion

Task description

[Feedback] Cancel Toast Persists After Process Completion

Background

The "Cancel" toast notification that appears when a Manual Trigger is executed remains visible even after the node processing is complete.
(While this is reportedly scheduled for future improvement, it's desirable for the toast, especially one with a "Cancel" button, to automatically disappear once the process is finished. Currently, the toast doesn't disappear unless manually closed with the 'x' button, leading to multiple toasts stacking up with consecutive operations, hence this issue.)

Additional notes (Optional)

Steps to Reproduce:

1. Execute any Manual Trigger.
2. Confirm that the "Cancel" toast notification appears.
3. Wait for the process to complete.

Actual Result:

The "Workflow submitted successfully" toast (initially the "Cancel" toast) remains displayed.

Expected Result:

The "Workflow submitted successfully" toast should automatically disappear once the process is complete.
