Here is a Facebook help document about editing privacy and settings for Business Integrations on your personal Facebook account: https://www.facebook.com/help/405094243235242.

Additionally, a workaround you can try is to use the "Custom" option in the Page field of the trigger step. This will let you type in or paste the "ID" of the page inside the field box. That's the quickest way to load a value to a dropdown list that doesn't appear as an option immediately.
