After decompiling, I discovered some APIs in a framework called DFRFoundation located under /System/Library/PrivateFrameworks, and a related method DFRElementSetControlStripPresenceForIdentifier. I find it quite difficult to get further, so I answer here only to let you know that the API for this is in a private framework. Hope someone would reveal the secrets someday.
