How do you create threads?

I’ve searched high and low and can only find developer documentation. Am I missing something obvious? I can create channels, I can create discussions, but I don’t see a way to create threads. Threads are enabled in administration. I’m just lost.

Hi,
an easy way to create threads is to hover over a message and go to the three dots menu on the right sight and select answer with a thread

is this the only way?
