Admin link extensions have been migrated to the Shopify CLI

Apps can now create and migrate to admin link extensions, which replace both admin links and bulk action links, which were previously created from the Extensions section of your app's Partners Dashboard.

Admin link extensions let you access the same functionality as admin links and bulk action links, but also let you localize links for users, manage links in your app's source control system, and manage their deployment with the Shopify CLI. To upgrade to admin link extensions, follow the tutorial on shopify.dev.
