I'm integrating UI Integration Cards into SAP Work Zone, and I'm trying to show data from Microsoft Outlook by calling the Microsoft Graph API. The problem now is that I need to request the /authorize and /token endpoint from the Microsoft Identity Platform to authorize the user and receive an access token to make request to the Microsoft Graph API. But when calling either endpoint, I get the error: "Access to fetch at '(requested URL)' from origin'(my URL) has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource. If an opaque response serves your needs, set the request's mode to 'no-cors' to fetch the resource with CORS disabled." I also tried calling the API with the 'no-cors' mode in the fetch function, but I got an 400 (Bad Request) response.
Is there a way to surpass getting blocked by the CORS policy?
