5        "description": "Credential description",
6    "context": [
7      "https://www.w3.org/2018/credentials/v1",
8      "https://schema.org",
9            "https://www.w3.org/2018/credentials/examples/v1"
10    ],
11    "type": [
12      "MATTREmployeeCredential"
13    ]
14  },
15  "federatedProvider": {
16    "url": "https://{{okta: domain}}.okta.com",
17    "scope": [
18      "openid",
19            "profile",
20            "email"
21    ],
22  "clientId": "{{okta: client_id}}",
23    "clientSecret": "{{okta: client_secret}}"
24  },
25  "claimMappings": [ 
26        { 
27            "oidcClaim": "name", 
28            "jsonLdTerm": "name" 
29        }
30
