How can I get realms on PS4 in Minecraft?

I downloaded the latest update, which includes the "bedrock edition" and thus also the crossplay function between switch, Xbox and PC. Only I couldn't find anywhere to go in a realm. Do you know where this function is? If so, then where. And if no, please tell me if and when it comes.

You have to buy realms yourself or be invited by jmd.
Look at the normal servers.

I'm in a realm. I can join the realm with my PC, my switch, my Xbox and my smartphone. Just not with the PS4 and I don't understand that, since the bedrock edition is now available.

It is currently NOT possible to create or join a realm. I tested it last weekend with a friend that I invited him to my realm. The invitation appeared to him both on the PS4 and on his cell phone, but he could only accept the invitation on his cell phone and join it in my realm. PS4 didn't work, even if we restarted Minecraft and then the PS4 itself. Realm is currently unavailable on PS4.

but it will be added in the near future.
