|

*
|

* function(array $attributes, array $author_contact, string $content): string
|

*
|

* Where:
|

* - $attributes is an array of attributes of the [share] block itself. Missing keys will be completed by the contact
|

* data lookup
|

* - $author_contact is a contact record array
|
||||
* - $content is the inner content of the [share] block
|
||||
* - Return value is the string that should replace the [share] block in the provided text
|
||||
*
|

* This function is intended to be used by addon connector to format a share block like the target network is expecting it.
