Xbox UI has been a bit all over the place on Series S/X (and XB1, which shares most of the same design).
It's not terrible by any means, but it can be unintuitive at times and the updates to improve things tend to be 'two steps forwards, one step back'.
Honestly, a bunch of indies self-labelling as 'triple i' feels a bit pretentious to me, but the intent seems good so I'm hoping it doesn't come off that way in practice.
