Proper way to set up simultaneous hand & controller input for Quest3?

Hi.
This topic might be redundant with the topic of this thread, but with the SDK updated to V62, the useful official documentation provided in the previous thread was deleted, and I can't find an alternative document. Also, the simultaneous hand & controller input has been released as an official feature, not experimental, so I started a new thread. I was able to make simultaneous input work on Quest Pro with SDK57, but it hasn't been successful with V62 & Quest 3 yet. (I sold my Quest Pro!) I confirmed that the feature itself works properly on Quest 3 as well with the demo published on the App Store, Interaction SDK Samples, but it seems that this sample project is not included in the samples for the v62 SDK. Am I missing something? If anyone has any cautions, useful information, or links regarding this matter, please share your knowledge.
