Core GameKit and installing Playmaker custom actions

Hi

I exported a prefab with Playmaker FSM from a project and imported it to another project using Assets > Import package > Custom package >..

All is working except that now if I look at the imported prefab's FSM there's one state that says "Missing action" Action name: CoreGameKitPoolBossSpawn

Core GameKit asset is imported to the project and I also imported the Playmaker_CustomActions.unitypackage from folder ..Assets\Plugins\DarkTonic\CoreGameKit\3rd Party Plugin Integration using the above procedure.

Core GameKit Playmaker actions should be in ScriptControl? There's none.

Maybe I did something wrong so to make sure, what is the step by step correct procedure to use Playmaker integrations?

There's no mention here: www.dtdevtools.com/docs/coregamekit/IncludedIntegrations.htm
