Is it possible to use Auth0 against Azure AD, with a SPA and a web api?

Hi - I have a Vue based SPA that authenticates against an Azure AD application. It needs to call a web api that must verify credentials and also extract azure security groups. I have the authentication part working, but I cannot get the autorization part working.

So I was thinking that maybe auth0 could help me.

I found this article but as far as I can tell it only handles the authorization part between the SPA and Azure AD. How do you verify the supplied bearer token with auth0 against Azure AD?

Any hints would be appreciated.

Kind regards
