The scenario is an unauthenticated SWA, with the ACA app doing the authentication "dance" with the IdP (redirecting to the IdP, being called by back by the IdP). Think SPA hosted on App Service, with the .NET part doing all OIDC.
Reading the documentation I am not sure if this is possible because https://learn.microsoft.com/en-us/azure/static-web-apps/apis-container-apps#unlink-a-container-app says "To prevent accidentally exposing your container app to anonymous traffic, the identity provider created by the linking process is not automatically deleted. " To me this sounds like my scenario might not be possible, or would this identity provider be on top of what I am doing?
Mostly what I want is an App Service-like scenario where I ignore EasyAuth and roll my own.
