Poe 2 early access

Hello fellow exiles,

First of all if this is wrong section - Sorry.

I just wanted to ask what preparations I need to be make to link my steam account with PS5 for POE2 early access? Since in one of the interviews Jonathan mentioned that it will be cross platform and we can play with our account from console and PC at any time, and all our glorious MTX will be transferred / shared between platforms. Or am I mistaken?

And will PSN be required?

If these questions were already answered a link to these thread will do.

Thanks.
Stay sane fellow exiles few more weeks until we see for our self's what GGG cooked for us in POE2 early access.
