Coinbase user - now I need a wallet to send bitcoin. Not do-able in Base app?

Been a coinbase user for years, just to buy and trade. Now I'm sending bitcoin to someone for the first time and not using coinbase for it due to needing to add full names for the recipient etc, which I dont have. So I read wallet (or base app as it is now?) was the easy option. I downloaded it, but I can't see the option to have a bitcoin wallet on there, only etherium. Googling showed that people have used base to send bitcoin so I don't know what I'm not seeing. All tutorials show a completely different UI and set of options to what Im seeing so arent any help.

Does anyone have any ideas?
