Readwise Official Plugin "Logseq Export": Export save date of each highlight?

Hello everyone,

I would like to export the save date of all my Readwise highlights that I export to Logseq. By default, Logseq returns, for example, “Highlights first synced by [[Readwise]] [[September 1st, 2020]]” as the heading and synchronization date for a page, but unfortunately no save date (to Readwise) for the individual highlights that appear below it.

Can anyone help me how I can change this?
