SSO options between mobile and web apps

I know that similar questions have been asked before but just wanted to check if there are any new developments or other options.

We have a requirement to enable SSO between a native mobile app and a web app embedded in a web view inside the native mobile app. This does not work because the web view has a different browser context from the one of the default OS browser used when performing the Universal Login authentication via the SDK, and the session cookies are therefore not shared.

My question is, since Okta does support this scenario via their Native SSO feature (Configure SSO for Native apps | Okta Developer), and since Auth0 is now part of Okta, would it be possible to leverage/integrate that capability into the Auth0’s CIAM system?

Alternatively, is it possible to create the session cookies based on the id_token, auth_token, and refresh_token returned by the SDK, and pass the cookies into the web view?
