As I understand it, recently Facebook has decided to remove the offline_access permission and has introduced a concept called long-lived access tokens which last a maximum of 60 days. Is there anyone who knows how to get this access token with the Facebook JavaScript SDK?

When your app uses Facebook Login to authenticate someone, it receives a User access token. If your app uses one of the Facebook SDKs, this token lasts for about 60 days. However, the SDKs automatically refresh the token whenever the person uses your app, so the tokens expire 60 days after last use.
In the Access Token Debugger that will open up, click on the 'Extend Access Token' button at the bottom of the page. A new access token should be displayed and the text above it should say that it never expires.
You can learn more about obtaining a user access token by implementing Facebook Login for Android. You can retrieve the user access token by inspecting Session. getCurrentAccessToken .
Long-lived tokens are valid for 60 days and can be refreshed as long as they are at least 24 hours old but have not expired, and the app user has granted your app the instagram_graph_user_profile permission. Refreshed tokens are valid for 60 days from the date at which they are refreshed.
There is a way to extend this to 60 days. described here: https://developers.facebook.com/docs/roadmap/completed-changes/offline-access-removal/ under Scenario 4: Client-side OAuth and Extending Access_Token Expiration Time through New Endpoint
Edit: In order to extend the access token you need to make the following request with your short lived access token:
