local_site_url is a function defined in ~/lib/python/cmk/gui/plugins/wato/notifications.py . I’m not sure if it is available from within the local plugins.

This should be possible at the head of the file there is then an import statement needed.
from cmk.gui.plugins.wato.notifications import local_site_url
