Usually, the Enter button will result in a newline, causing the response to be empty string.

echo -e "(corona) > Press "Enter" to Exit... c"
read handler
if [ "$handler" == "" ]; then
    echo -e "(corona) > Exiting... c"
    ...
fi

You can also combine the echo/read to use the prompt option of read

read -p "(corona) > Press "Enter" to Exit..." handler
if [ "$handler" == "" ]; then
    echo -e "(corona) > Exiting... c"
    ...
fi
