Passkit get update with refresh token

We have a digital membership card stored in apple wallet which get update from our web service with an access token. The access token expired in few days and required a refresh token to renew it. The refresh token expires in 60 days. Otherwise, we will need customer to re-login their membership account in order to get a fresh access token and refresh token again.

  1. How can we store both the access token and refresh token in wallet?
  2. After the access token or the refresh token is updated, how can we update card data in wallet?
