Canon Eos R5 mark II livestream how to?

Hi, after preordering the mark II to the shop i'd bought my mark I, i'm the proud owner of a mark II (I resold the mark I to the shop) for less than a week.

I like how they change some buttons. It's heaven to switch between photo/video compared to the mark I.

I have questions regardent livestream option.
When i want to set it up via camera connect app i got an error message about HDMI. I thought you could livestream with phone and camera, without computer?


Does someone successufully set livestream option ? How to ?

Also do you know if you can both record video on card AND livestream at same time ?

Thanks for your help.
