Thunderbolt 4 Dock - Monitor Question

Hey all, Not sure if this is where this goes since this product could go a few places, but I have the Thunderbolt 4 Dock & a Samsung G9 5120x1440 monitor. Works great. I'd like to add a second monitor to my setup (same G9 5120x1440) but given that the dock says it supports 4k, I'm concerned this other monitor may not work. Any idea if it'll fly? Thanks!
