Is there any extension target in order total summary. I am not able to find any such target in documentation.
I am referring from this documentation https://shopify.dev/docs/api/checkout-ui-extensions/2023-10/targets
I need to add some detail just before total or after tax detail.
The closest target extension would be the purchase.checkout.reductions.render-after target that is rendered in the order summary, after the discount form and discount tag elements. There doesn't appear to be an target for the specific area you're looking for, but I've added this as a feature request for the product team.
Hope this helps,
