At the very first, I've installed the old version (the old Mendeley OAuth version) plugin and cannot get any access token from the plugin.... So, I posted my question to the support page of this plugin and get prompt reply that a OAuth2 version will coming soon.
Now I've installed the new verion (0.9). In the API Keys section of WP Mendeley setting, a URL can be used to apply a Mendeley application. After receive the client ID and secret from Mendeley, you can request the access token.
I use the [mendeley type="own" groupby="year" sortby="year", sortorder="desc"] as the shortcode in my post, and it works.
