Passing msal auth to webview2. Pca or confidential client

[JohnDizzle]

I have a desktop app that I am successfully authenticating utilizing a broker for authorization through a public client. I have the authentic result; which gives me user identifier, access token, and user principal name. I asked copilot and it recommended adding cookies and then says adding a header to webview2 request handler. All were successful with the addition, but Microsoft when going to office apps like word and outlook it still wants a login. I’ve done this is a react app with local storage or
Persistent caching as well. But winui3 desktops that host a webview2 for its primary functionality doesn’t cross authenticate.
Please help me ?
