Hello,
I am sorry but this does not work now.
Facebook’s developer’s blog says that no new apps will be allowed to do this, and existing permissions were revoked in August 2019.
-------------
Deprecation:
The publish_actions permission will be deprecated. This permission granted apps access to publish posts to Facebook as the logged in user. Apps created from today onwards will not have access to this permission. Apps created before today that have been previously approved to request publish_actions can continue to do so until August 1, 2018. No further apps will be approved to use publish_actions via app review. Developers currently utilizing publish_actions are encouraged to switch to Facebook's Share dialogs for web, iOS and Android.

This means they require people to actively share their work manually.
We will be removing that app totally shortly.
You now need to share using the FB button on the image page manually using the FB icon on the right of the image page
You have a button on your Facebook business page under the cover image. You can have that link to your store here direct.

You can get very fast answers to all queries by asking the members, here https://fineartamerica.com/posttopic.php?newtopic=true Note this is a public way of asking so do not ask private questions there.
