Use JWT Token to call ReST API from 3rd party Application

Content

Hello,

I am currently using basic authentification (user/paswword) to call some ReST APIs. (from postman or other third party application)
I want secure this identification and use JWT token..
So, i reviewed documentation here : https://docs.oracle.com/en/cloud/saas/applications-common/20d/facsa/api-authentication.html#FACSA4182699
and found that I should configure inbound authentification in security console.. Is it correct ?

Then, I followed the steps described in and faced following issues in "API Authentication Configuration" UI:

oracle.apps.hcm.ase.protectedModel.common.core.rest.exception.WebServiceException: oracle.apps.hcm.ase.protectedModel.common.core.rest.exception.WebServiceException: {"STATUSCODE":"40061","ERRORCODE":"WSM-27892","MESSAGE":"WSM-27892 : Access permission is denied to access \"tokenissuertrustGLOBAL\".. Root cause is : WSM-02084 : Access denied. Permission \"oracle.wsm.security.PolicyManagerPermission\" is required to access the wsm policy manager \"DocumentManager\" method \"writeDocuments\"."}
