Those are general app creation guides. There are multiple steps, options and permissions that I need to select/enable while creating the app depending on the use case. For e.g. which app type to create, which use case to select and which permissions do we need to enable the functionality etc...

For an example, please see the guide given by FS Poster that works with their plugin. https://www.fs-poster.com/documentation/facebook-personal-app-method-fs-poster-wordpress-plugin

Go through that guide - you can see the kind of options that need to be selected while creating the app.

So which way should I create the App for the Share Selection text to work?

Hello

Is there any guide to create the Facebook App required for "Share Selection Text" feature?
