Why do I receive a 403 forbidden response when calling this endpoint with Angular, using the Microsoft Graph REST API?
Question
Main question
I have been working on integrating the Microsoft Graph REST API into an Angular (version 10) application. I have followed the instructions given by the following tutorial on how to connect the Angular application to Microsoft Graph and sign in a user over Azure AD (by registering the app in app registration).
I have followed the tutorial every step of the way, and I have now decided I want to extend the application by getting the Teams chats I am a member of , over HTTP. I decided to create a simple test by printing out the results of the call to the browser console, but when I attempt to call it there is a HTTP 403 response ( "Failed to get license information for the user. Ensure user has a valid Office365 license assigned to them." ) I have attempted to do this with a student Office 365 account, and with my personal Microsoft account, but I continue to receive the same HTTP response.
Attempted solutions
When tested in the Graph Explorer, the correct response is received. I have added the student account to a Azure AD tenant where the personal account is a Global Administrator.
I have attempted to call the aquireTokenPopup , aquireTokenSilent and aquireTokenRedirect in the Method screenshot but to no avail (I still receive a 403 HTTP Forbidden response.) I have also looked through the documents listed on docs.microsoft.com , and looked at the different documentation for this 403 response, but I have not been able to make head or tail of what the 403 responses may mean - the student account has a valid Office 365 tenant while my personal account does not and I get the same response.
Why do I receive this response, even when I have given permission in the Popup, as well as configuring to allow the endpoint in Azure?
Has something been wrongly configured?
Have I used the wrong type of authentication? (should I have used Azure AD B2C?)

You must meet the following two points:
You must use a work or school account, it does not support Microsoft personal accounts.
Your account must have an Office365 license.
