On a Lightning Record Page I added the Standard button 'Add To Campaigns' under the Salesforce Mobile and Lightning Exprience Actions section. When i navigate to the page, in the highlight panel I don't see the Add to Campaigns button. Any thoughts? 

I see that  Camapign Memeber is not available for selection in the Object Specific Action, neither is it available for selection in the Global Action. 

I tried replication the Add to Campaign buttons through process builderrr/Flow, without success. 

Any other way to replicate the Add to campaign button as a quick Action on the record Detail page? 

Thanks!
