You need to enable the desired jfbconnect provider plugins in order for the SCSocialWidget module to populate. For example, if you want Facebook social widgets such as the Share button or Page plugin, you'll need to enable the 'Facebook' plugin. If you want to set up a channel for the Facebook Page, you'll need to enable the 'Facebook Business' plugin.
You can follow our configuration guide in the
Quick Start documentation section
. Other sections like Social Widgets for the SCSocialWidget and Social Sharing for the channels should also help.
