Can't find Matter binding?

[glad pike]

Okay I feel really silly posting this question.
I heard Matter binding had been released as a beta feature, but I can't find it.

I've been using Homeassistant for a year with my Inovelli and Nanoleaf Thread devices, so I know ow my way around. I've updated to beta releases of both HA and Matter, gone to the appropriate entities, and there is no binding button.

What painfully obvious thing did I miss?

Aha nevermind, I found it! I didn't know that you needed to go into the endpoints till you found the one with the binding item. This wasn't obvious.

Whew!
