could you please enhance your social connector to be able to make functional mentions in LinkedIn posts?
Actually it is not possible, the mentions are presented as inactive text only so far.
Citing ClickDimensions last answer:
The social connector is currently unable to tag individuals in the manner that you've inquired about. The reason for that is that we would have to connect to LinkedIn/Facebook/Twitter, etc while constructing that post in order to pull in the "tag" information and generate that link. Currently, the connector does not allow us to connect directly to social media platforms in that manner.
