Connect a Mac and a Watch via Core Bluetooth

Hello! I currently have a pair of apps that can connect a Mac and an iPhone and communicate to each other. I've been trying to do the same between a Mac and a Watch.

In my current implementation, the Mac is the central and the iPhone is a peripheral. But according to some internet search, it seems that Watch can only be the central. Is this true, and still the case now, please? If so, can I use the Watch as the central and the Mac as a peripheral?

Thank you!
