Using a USB-C hub with a Samsung Galaxy phone - Will this work?

[connda]

Outside of computers I stay pretty dumb about current technology.

I've got a Samsung Galaxy phone running Android with a single USB-C connector.  I want to port the phone's screen to an external computer monitor using a HDMI cable but I also need to input an audio signal from my guitar amp into a music program that I run on the phone via a standard USB-A cable.  I figure that a USB-C multi-port hub will do the job - maybe or maybe not. 🤔 The USB-C multi-port hub would have both an HDMI and USB-A port, but?  I have no idea if the phone can handle both input and output in this manner.  Thoughts from more tech-savvy folks out there than myself?

Note: I know the phone can hook to a TV via "Smart View" but I don't have a TV, only a computer monitor.
