No refresh token when using Passwordless/OTP grant through SMS

Hi!

I’m trying to setup the passwordless/otp flow for my react native app and everything works except for the refresh tokens which are not included in the response from Auth0 API.

These are the exact requests:

POST: https://{AUTH0_DOMAIN}/passwordless/start
{
  "client_id": "My Id",
  "connection": "sms",
  "phone_number": "+46XXXXXXXX", 
  "send": "code", 
  "authParams": { 
    "scope": "openid profile email offline_access"
  }
}

POST: https://{AUTH0_DOMAIN}/oauth/token
{
  "grant_type" : "http://auth0.com/oauth/grant-type/passwordless/otp",
  "client_id": "My Id",
  "username":"+46XXXXXXXX", 
  "otp": "XXXX",
  "realm": "sms", 
  "audience" : "https://{OUR_DOMAIN}.se",
  "scope": "openid profile email offline_access" 
}

Does anyone know how to include the refresh token in the response? I’m currently getting the following response:

{
"access_token": "eyJhbGciOiJSUzI...",
"id_token": "eyJhbGciOiJSUzI...",
"scope": "openid profile email",
"expires_in": 86400,
"token_type": "Bearer"
}

I am dealing with the same issue, do we have a way to implement passwordless sms/email otp codes and refresh tokens? If found that some posts that said that is possible and other that says it is not possible.

If is possible please tell us how we can achieve it. If not, is there a way to implement similar passwordless feature without having the users to login every single day?
