Thank you @Mubashir_Hassan for your response. I have one more question and a suggestion that I would like Shopify to consider regarding App Blocks and App Embed Blocks.
Once the merchant has already added the app block, is there any URL that can directly take them to the existing app block inside the Theme Editor instead of showing the “Add App Block” flow again?
