Default value for field type reference

Hello, is there any way to add a default value for the field type “Reference” (Array)?

eg. I have a Reference field called “Tabs” and whenever a user with an editor role creates a page, the “Tabs” field will have default values declared.

I stumble upon the Building a backend app tutorial and the demo discusses “identities and events to add default values to entries”


Solution - create a separate app and attach it to your contentful space. Attach a webhook whenever an entry is created, it should add a default value that is based on the value from the extension app you created.

This is enough info for me to move forward with this!
