You can set following OG tags for the CMS detail page (dynamic page):
Title (title of the page)
Description (description of the page)
Cover image (OG image on social media, etc.)
To begin with, please make sure that the page you are trying to set OG settings is a "dynamic page" and that you select "Page Settings" (not Site Settings) from the Settings panel on the right of the editor.
For the title and description, click on the + icon and select the proper properties.
You can also add text to be displayed on all dynamic pages.
Select the cover image by clicking on the properties listed.
After configuring the above settings, check if the settings are reflected in the live preview. If there is no problem, please make sure to publish your site so that they are reflected on the production site as well.
