Nvidia-smi command not found despite installing CUDA

I installed CUDA on my Win10 machine this morning to use CuPy. Running nvcc --version gives an output, and so does conda list cudatoolkit. However, running nvidia-smi in a conda environment gives the error command not found. I know that nvidia-smi.exe exists on the machine in C:/Program Files/NVIDIA Corporation/NVSMI/. How should I resolve this?
