The structure of creating a deep link to allow online store admins to add an app block/section to a theme template is clear (documented here).
However, when the link is clicked the theme editor will open the required template (for example: 'default product') but the preview pane will show a random page for that template (for example: random product).
Is there a way to set the 'previewPage' query param to force the theme editor preview to open to a specific page when deep linking to enable an app block/section?
Simply adding the 'previewPage' param to the deep link did not work:
https://<myshopifyDomain>/admin/themes/current/editor?template=${template}&addAppBlockId={uuid}/{handle}&target=newAppsSection&previewPath=%2Fproducts%2Fsome-product-handle
