The meeting minutes announcing the policy briefs are dated 21 March 2023 https://www.un.org/sites/un2.un.org/files/24thunenmtg_minutes_21march2023.pdf https://www.un.org/sites/un2.un.org/files/24thunenmtg_minute... and the overview document https://www.un.org/sites/un2.un.org/files/nesd_overview_20_march.pdf https://www.un.org/sites/un2.un.org/files/nesd_overview_20_m... has "20_march" in the filename, so I think publication must've happened somewhere around that time.
