Let Dex Copilot build follow-up lists from LinkedIn messages and post comments

Dex Copilot should be able to identify people who engaged directly through LinkedIn messages or comments on the user’s posts within a chosen date range.

Desired outcome:

• Return a bounded, reviewable list of matching contacts.

• Include a reference to the relevant message or comment for context.

• Keep the workflow read-only by default so the user decides who to follow up with.

Current gap: Dex syncs LinkedIn connections and contact updates, but LinkedIn messages and post-comment engagement are not exposed to Copilot for this workflow.
