Credential Offer indicating a grant type

Issuer gives clear guidance to the wallet which grant flows it wants the wallet to do

if the Issuer wants the wallet to do only one of the grant (pre-authorized_code or code), send one of the parameters
if the Issuer can do both grants and wants the wallet to choose, put two parameters

Syntax can look like:

{
  “credential_issuer“: “example.com“
  “grant_type”: {“pre-authorized_code“, “code“},
  “pre-authorized_code“: “string“, //mandatory
  “user_pin_required”: true, //optional
  “issuer_state“: “string“ //optional. used to be called op_state
}

or

{
  “credential_issuer“: “example.com“
  “grant_type”: {“code“},
  “issuer_state“: “string“ //optional. used to be called op_state
}

or

{
  “credential_issuer“: “example.com“
  “grant_type”: {“pre-authorized_code“},
  “pre-authorized_code“: “string“, //mandatory
  “user_pin_required”: true //optional
}

a following structure might work but than code object will be empty when issuer_state is not present.

{
  "grant”: {
    “pre-authorized_code“: {
      “pre-authorized_code“: “string“
    },
    “code“: {
    }
}
