Linkedin page metrics by Date - what date field to use

Good Morning,

I am using LinkedIn connector to power bi.
Trying to re-create analytics metrics by date:

Below is my connection:,post_id,account_name,share_clicks_count,share_comment_count,share_impression_count,share_like_count,share_count,share_description,share_text,share_title,share_unique_impressions_count&_renderer=powerbi

the date field seems to show data only for the dates when post was created.
I would like to show analytics metrics for every date (from present to last 28days, as in parameter),
My question is what date field I should use?
I am on free trial right now, and the numbers for likes, shares etc by day does not match to the ones in Linkedin Analytics.
