@sebastienlevert to evaluate whether we need that for preview or GA or post GA and prioritize it accordingly.

Definitely POST-GA. I think Azure Identity should be good enough for now.

I implemented something like this in a react app that may be related https://gist.github.com/lroos/0e0cec0346803368b3268bdae8a85101; it's a TokenCredential type that I passed into AzureIdentityAuthenticationProvider. I just had to set the allowedHosts to my endpoint origin. This on the right track?

Hi @lroos
Thank you for using kiota and for reaching out.

This could work, but adds another additional level of indirection that is not needed.

The suggestion here was instead to create a new package, that DOES NOT have a dependency on azure core, but instead on MSAL, and implement both BaseBearerAuthenticationProvider and IAccessTokenProvider with the primitive MSAL is using : ClientApplication

Is this something you'd like to submit a pull request for provided some guidance?
