Why would I be unable to right click using the touchpad when using EndeavourOS with XFCE4 on a NexDock?

When clicking using the bottom right side of the touchpad on my NexDock nothing happens when using EndeavourOS with XFCE4. When connected to Windows I am able to right click using the touchpad without issues.

Does anyone know how I can remedy this? I feel like it's probably something obvious.

I tried looking under the Mouse and Touchpad settings application but don't see anything that looks relevant. The NexDock does appear as multiple devices. SINO WEALTH NexDock Touchpad Keyboard Consumer Control, SINO WEALTH NexDock Touchpad Keyboard Mouse, and SINO WEALTH NexDock Touchpad Keyboard Touchpad are all listed but only give me the option to switch hands or adjust pointer speed.
