Heya, I want to make an api call with a Bearer access token from Auth0. Is it appropriate/idiomatic in re-frame to use an effect handler for retrieving an Auth0 access token when using getTokenSilently from the auth0-spa-js library (which returns a promise)? So something like this?

(rf/reg-fx
 :fetch-access-token
 (fn [on-success]
   (-> (.getTokenSilently client)
       (.then (fn [result]
                (on-success result)))
       (.catch (fn [error]
                 (js/console.error "Error fetching access token:" error))))))

(rf/reg-event-fx
 ::api-call
 (fn [{:keys [db]} _]
   {:fetch-access-token (fn [token]
                          (rf/dispatch [:api-call-token token]))
    :db (assoc db :api-call-pending true)}))

(rf/reg-event-fx
 :api-call-token
 (fn [{:keys [db]} [_ token]]
   {:http-xhrio {:method          :get
                 :uri             ""
                 :headers         {"Authorization" (str "Bearer " token)}
                 :timeout         8000
                 :response-format (ajax/json-response-format {:keywords? true})
                 :on-success      [:success]
                 :on-failure      [:failure]}
    :db  (assoc db :api-call-pending false)}))
