The declared possibilities are supported. The described disadvantage is more of a wish, the manufacturer did not promise such functionality. I'm using a Dodocool HDMI monitor adapter and it occupies one of the two USB-C ports on the MacBook Air M1. If you connect Belkin to the USB-C port on this adapter, then the laptop is charging, but ethernet does not work. Therefore, Belkin needs to be connected to the second port of the laptop, and there is nowhere to connect the phone - you need to choose either Ethernet or a phone.
