Welcome to the thunderdome!!!! 😄
The Nvidia app itself is just a window executable so typically won't work. Linux drivers for Nvidia are an unfortuante small nightmare to navigate (hence the thunderdome :P). You'll need to install the proprietary drivers or open drivers for the card and can install nvidia-utils package to get extras like nvidia-smi or nvtop for seeing utilization.
Reason this ends up being difficult is most often if the nouveau drivers are installed and are loaded/loading ahead of the other drivers you are trying to use, typically packages are named based on driver number.
Anyhow TLDR there is a GUI for switching driver versions and is probably easist way to give it a shot but do expect to have some troubleshooting since it isn't always a smooth going process (can often install drivers and have it crash the display-manager/gui/initial login so make sure are ready to do some troubleshooting and able to get anything critical off the drive(s) before proceeding).
