List the user's LinkedIn posts, newest first: posts created in Taplio (status scheduled, sending, or sent) plus posts published directly on LinkedIn, which always come back as sent. A draft becomes a post once it is scheduled or published. Taplio posts are ordered by when they were created in Taplio, posts published directly on LinkedIn by when they went live. With status scheduled and from or to set, the window applies to the scheduled date and posts come back soonest first. LinkedIn-native coverage is the last 90 days and relies on a daily sync, so a post published in the last few hours may not be listed yet. Engagement metrics are not included: use get_post_analytics for impressions, likes, comments and shares. Also useful before drafting, to avoid repeating recent topics and match the user's established voice. media_type reports each post's format (text, image, video, document or article; absent when the format cannot be determined). media lists the post's images, video or document as durable urls, for posts created in Taplio and posts published directly on LinkedIn. It can be empty even when media_type reports an image, video or document, when Taplio does not hold a copy of that media yet: do not call again to wait for it, describe the post from its text and media_type.
