You can also get USB-C to DP/HDMI/VGA/DVI adaptors that support USB passthrough. "Most" (?) modern phones support DP-over-USB-C now and some even open a DeX-inspired desktop environment when connected (which even if it's broken/buggy like Huawei's implementation means the external display is driven at its native resolution, so media plays properly).
The adapters on AliExpress run $6-15 and are entirely adequate for the task IME.
