Umrbaco 14 SendingContentNotification alternative for setting default values in property editor

Questions
1

Hello i am searching for a solution that allows me to set a default value when initially using a property editor to change the content or when no value is set when saving.

I came across this page on in the documentation of umbraco 14 EditorModel Notifications | Umbraco CMS . It shows how to use the SendingContentNotification to set a default value before the user sees the editor in the backoffice. But when i tried to implement it i was not able to find the SendingContentNotification.

I also found this github issue indicating it was removed:

Does anybody now a solution for setting a default value besides the SendingContentNotification?

Thanks in advance
Reinhard
