Hi all, We are using the Delivery API with Astro to create a website. We also want a preview environment, which will be hosted on a different resource which makes use of the preview header supported by the delivery API. When looking at the documentation you are able to add extra URLs for preview to the backoffice: https://docs.umbraco.com/umbraco-cms/reference/content-delivery-api/additional-preview-environments-support. But I couldn't find any information as of how backoffice authentication can be aplied? Does anyone have any experience with this? Thx in advance!

I don't think its possible for v14+ https://github.com/umbraco/Umbraco-CMS/issues/17035
