Trying to implement CSRF protection with Spring Security and React frontend

I'm trying to get CSRF protection to work using spring security but I keep getting a 403 forbidden error when trying to make a post request to a csrf protected endpoint using postman.

On postman, there are two cookies present - SESSION and XSRF-TOKEN and I also include a X-XSRF-TOKEN header while making the post request and still get a forbidden error. I'm not currently sending any requests from the SPA directly. Just using postman for now....
