Support for Access and Refresh Token in JWT Format.

Hi,
Can we generate access and refresh token in JWT format instead of normal string? Also, how can we return JTI values?
Thanks.

**Current Format:**
------------------------
{
"access_token": "6hdWtMlPL1cXrFgZpeaXkkVI0cys5JPEOCZe17FDID",
"expires_in": 3600,
"refresh_token": "TL4GIU9RbZZ2TXzkF4s2gsEGIiV4VezrL3HaMlmTfsmMpTwX",
"scope": "checkcard",
"token_type": "Bearer"
}

**Required Format**
----------------------
{
"access_token": "eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ6.eyJleHAiOjE4NzE2MTcwNzYsInVzZXJfbmFtZSI6Ik5FUFMiLCJhdXRob3JpdGllcyI6WyJVU0VSIl0sImp0aSI6ImU0ZDYwODk5LTllNjctNDJhYy1hMzZmLWM3ZjFjODE4NWI4OCIsImNsaWVudF9pZCI6Ik5FUFMiLCJzY29wZSI6WyJhcGkiXX0.sTuPN5qdLNplTG5BBf1YwYjS9X0b1APMz8nzNNTMGjs",
"token_type": "bearer",
"refresh_token": "eyJhbGciOiJIUzI1NiIsInR5cCI9IkpXVCJ6.eyJ1c2VyX25hbWUiOiJORVBTIiwic4NvcGUiOlsiYXBpIl0sImF0aSI3ImU0ZDYwODk5LTllNjctNDJhYy1hMzZmLWM3ZjFjODE4NWI4OCIsImV4cCI6MTY3MTYxNzI1NiwiYXV0aG9yaXRpZXMiOlsiVVNFUiJdLCJqdGkiOiI4MGMyNDNkMy1lMWI1LTRlYjctOTU5ZC0zNGJkOWM3NWRkMzMiLCJjbGllbnRfawQiOiJORVBTIn1.gARNnr_LK1hLFJXH_ULBcOvV2CV0xn08ajPee2shL6Q",

"scope": "api",
"jti": "e4d60899-9e67-42ac-a36f-c7f1c8185b88"
}

Example guidance would be much appreciated. Tx.
