JWT Validation missing fields

When trying to do curl [GET] request to validate:

{
    "jwt": {
        "exp": 1606240095,
        "iat": 1606236495,
        "iss": "acme.com",
        "jti": "XXXXXX-XXXX-XXXX-XXXX-XXXXXXXX",
        "sub": "XXXXXX-XXXX-XXXX-XXXX-XXXXXXXX",
        "authenticationType": "PASSWORD",
        "email": "domgolonka@domgolonka.com",
        "email_verified": true,
        "preferred_username": "domgolonka"
    }
}

The above shows the email, email_verified, preferred_username, & authenticationType fields.

When trying to it using the client:

*fusionauth.JWT=&{<nil> 1606238646 1606235046 acme.com XXXXXX-XXXX-XXXX-XXXX-XXXXXXXX 0 map[] XXXXXX-XXXX-XXXX-XXXX-XXXXXXXX})

There are missing fields from the above.

This one is super annoying. Actually, it makes /oauth/userinfo endpoint useless.

I agree, this is something we'd like to solve. If you have some ideas how to solve it - input is appreciated.

Here is the current struct def:

go-client/pkg/fusionauth/Domain.go

Line 1724 in 840527e

type JWT struct {
