Available permissions:

KeyValueStorePermission.get

This permission allows your service to get values from the key value store.

KeyValueStorePermission.set

This permission allows your service to set key value pairs in the key value store.

KeyValueStorePermission.delete

This permission allows your service to delete key value pairs in the key value store.
