Re: Access for an app not available in Privacy Settings
See how to: Control access to information in apps on iPhone - Apple Support
Eg: says:
"You control whether third-party apps have access to information in Contacts, Photos, Calendar, and other apps.
Review or change access to information in apps
The first time an app wants to use information from another app, you receive a request with an explanation. For example, a messaging app may request access to your contacts to find friends who are using the same
app. After you grant or deny access, you can change access later.
- Go to Settings
> Privacy & Security. - Tap a category of information, such as Calendars, Reminders, or Motion & Fitness.
A list appears showing the apps that requested access. You can turn access on or off for any app on the list."
The above article has more info. on how to: "Review how apps are using the permissions you grant them"
