Feature: Host AssetLinks on Auth0 custom domain with relationship “delegate_permission/common.get_login_creds”.
Description: Allow developers to add custom entries to the https://EXAMPLE_DOMAIN_NAME/.well-known/assetlinks.json file on the Auth0 custom domain.
Use-case:
When moving from one custom domain to another, or when you want to move from an existing domain to a new domain, it is helpful to have browsers suggest credentials of the old domain at the new domain. This can be accomplished using affiliated domains via Asset Links on some platforms. See Enable Chrome to share login credentials across affiliated sites - Chrome Developers for more details.
