Flask-Admin: How to get the object being edited in validate_form

def validate_form(self, form) -> bool:
    """Validate form."""
    if not super().validate_form(form):
        return False

    if form.scheduled_from.data >= form.scheduled_to.data:
        message = (
            "'Scheduled From' cannot be greater than or equal to 'Scheduled To'"
        )
        flash(message, "error")
        return False

    # HERE I NEED THE OBJECT THAT IS BEING EDITED
    
    print(form._obj)
