On more digging I found that when I add Authorization bearer token in the header I get this error...

You need to go to Platform Features tab -> Click on CORS and add your FrontEnd URL to the list of Allowed Origins.

If you add * to CORS list you have to remove all the other URLs. Otherwise neither of them are applicable
