Summary:
Added noDeviceErrorMsg as a JSX.Element that will display 'No device found' if there are no devices detected. It is an empty JSX.Element otherwise and nothing is displayed as shown in the video.
I am using a JS variable as a JSX element in this diff. This simplifies the if else checks needed inside return, and reused the same styling we have.
