Call Microsoft Graph API from Actionable Message - outlook

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?

(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']});

Answer 1

Regardless of how you generate the Adaptive Card, you cannot use the Microsoft Graph API from the context of Outlook using Outlook Actionable Messages :

Answer 2

Currently teams does not support http card action. Please go through this documentation for supported card actions.
