{
"sub": "admin",
"iss": "/C=US/ST=New Jersey/L=Bridgewater/O=Oracle/OU=UGBU/CN=nms-ofs_admin/emailAddress=nms-ofs_collaboration@oracle.com",
"aud": "ofsc:ofsc-fc776e.test:demoauth",

}
Note: The "sub" will be the originator of the JWT token. Refer to the next section for extra configuration in regard to this value. The "aud" contains "ofsc:{instance}:{ofs_ClientId}", as shown on the Applications screen. The "exp" is the epoch timestamp value, in the value above it converts to Thursday, February 3, 2033 3:43:18 PM time.
6. After the assertion key is generated, include it in OUTL-BRT-NMS_OFSC_ConfigProps for the property chat.notification.assertion and property chat.notification.grant_type : urn:ietf:params:oauth:grant-type:jwt-bearer.
Note: As a pre-requisite, signed certificate and private key from the client server are required for configuration.
