Call Microsoft Graph API from Actionable Message

Question

I'm trying to send an email using Microsoft Graph API from an action in an actionable message. (So send an email from a button in an email) However I'm always receiving a 401 Error. I tested the graph API in normal setting and the Auth token is valid, but here it seems to work differently.

Is it possible at all to achieve this?

                        },
                        {
                            "name": "Content-Type",

                        }
                    ],
                    "body": "..."
                }
            ]
        }
    ],
    "padding": "None",
    "@type": "AdaptiveCard",
    "@context": "http://schema.org/extensions"
}

(Edit) This is how I get the token:

Providers.globalProvider = new TeamsProvider ({
    clientId: {my client id},
    authPopupUrl: '/auth.html'
});
const token = await Providers.globalProvider.getAccessToken({scopes: ['Mail.Send', 'Mail.ReadWrite']});

Regardless of how you generate the Adaptive Card, you cannot use the Microsoft Graph API from the context of Outlook using Outlook Actionable Messages : https://github.com/microsoft/AdaptiveCards/issues/5674
