The other way is to create a new fan page only for the app and then follow the screenshot I’ve attached above. But I think it isn’t right to create new fan page only to connect the App to another page
To create a fan page for your App, go to Developers Dasboard, “Edit Application”. Then on the left is a section “App Details”Then navigate to “Contact Info”, where is the button “Create Facebook Page”
And to the previous post: I’ve also seen a 3rd party tool which created the connect link automatically after filling the App ID in. I’ll try to look for it.
EDIT: I’ve found the tool, but it doesn’t work anymore.
