*
* Using "mongodb-stitch-browser-sdk"
*
* ```js
* const client = Stitch.initializeDefaultAppClient('<your-client-app-id>');
* client.auth.loginWithCredential(...)
*
* const sdk = new ChartsEmbedSDK({
* getUserToken: () => getRealmUserToken(client)
* })
* ```
*
* or using "realm-web"
*
* ```js
* const client = new Realm.App({id: '<your-client-app-id>'});
* client.logIn(...)
*
* const sdk = new ChartsEmbedSDK({
* getUserToken: () => getRealmUserToken(client)
* })
* ```
