Email notifications: How not to receive notifications for automatic actions

Dolibarr inserts the events added automatically into the agenda. We have enabled automatic notifications when actions are added to the agenda. Email notifications are also arriving for events automatically inserted by dolibarr


(see attachment). For example, if a colleague enters a supplier invoice, notifications will arrive. We only need to receive notifications of manually entered events. How do I exclude notifications of automatically inserted events?

Thank you
