Afaik you can crrate an account without a number.

No. You can just hide it from other users in group chats now (and perhaps 1:1, didn't yet check but you still need one to sign up)

Where is the option for group chats please?

[Obscurity4340]

Does that require the sealed-sender thingy?

[matricaria]

Not yet, but they are working on that.
