Auto post to FB page only instead of profile

Hello —

I want to auto publish posts to only one of several FB pages I administer, but only “Profile Page” appears as an option in the plugin settings field called “Select Facebook Pages for Autopost.”

I tried following the instructions here for configuring which of my FB pages I would like the autopost to appear on:

I’ve created the Facebook application and entered the app ID & secret, but I don’t see a field in the plugin settings page where I enter my Facebook ID.

Can you help? Many thanks!
