Facebook Feed: Unable to get credentials from access token

Hi,

I was trying to get the Facebook post feed working and I followed every step here: https://essential-addons.com/elementor/docs/facebook-feed/

I am able to generate the access token where it says the token is valid when checked by the debugger. However when putting the access token into the credential page: https://app.essential-addons.com/facebook/ , I am unable to retrieve any credential.

It would be great if I can get some help.

Thanks
