MacBook Pro 2015 docked to Acer H277HU not able to detect external SSD through USB 3.0

I have my MacBook Pro docked to the H277HU monitor through HDMI and would like to be able to keep my external SSD connected to the monitor as opposed to my laptop. However, my MacBook can't seem to detect the SSD when it's connected to the monitor through the USB 3.0 port. The external SSD is a Samsung T5 Portable 1tb. It shows that it's receiving power from the USB port/monitor but my laptop doesn't detect it. I've also tried connecting my Logitech keyboard and mouse through their unified receiver in the same USB port, but my MacBook doesn't detect those either. Is it something in the settings that I am overlooking? Could I have a defective monitor? I have seen people use the USB 3.0 port with this same monitor to connect external storage and keyboard/mouse so I know it's possible. Would I need to connect to the monitor through USB-C instead of HDMI- could that have something to do with it?
