PC Borderlands 3 Crossplay?

I wanted to ask if the crossplay already works with borderlands 3? If so, how can I play with my buddy (Xbox) on a PC? Anyone have any idea?

As far as I know there's only a crossplay between Steam and Epic version. But I'm not really up to date either

In March 2020 there was an update to the game that you can do crossplay (even in Borderlands 3 a setting to switch on and off in the menu). But now the question arises for me, how is that supposed to work now! ^ - ^ Is the shift account enough?! ^^

Thanks to the magic of PC crossplay with the help of SHiFT, you can team up with other PC players, regardless of whether they bought the game on Steam or in the Epic Games Store.

It's on Borderlands.com

So only Crossplay on PC means not to console
