I've tried multiple OEM cables (both USB A and C), and cubes (5w and 20w), and also tried connecting to my MacBook Pro M1.
Nothing. No lights, no sounds, nothing. I feel like Steve Jobs would've had someone pilloried for this. Contacted support and escalated to a complaint. Also sent feedback. I expect to hear back from them some time after the polar ice caps melt.
I've been without a phone for a week now and it's kind of liberating. It hasn't been as bad as I thought it would be. There have been a handful of occasions where I was inconvenienced but whatever. My iPad Pro is now my phone.
