+#### Refresh access token
+
+You could use a refresh token, to get a new token from the oauth server when token expired.
+
+```typescript
+sdk.refreshAccessToken(refreshToken).then((resp) => {
+ const token = resp.access_token;
+ // Do stuff with new access token
+});
+```

 #### A note on Storage
 By default, this package will use sessionStorage to persist the pkce_state. On (mostly) mobile devices there's a higher chance users are returning in a different browser tab. E.g. they kick off in a WebView & get redirected to a new tab. The sessionStorage will be empty there.
