Retrieve the top Twitter trends for a specific location and displays them in an embed message on Discord. Inside the main function, it first initializes a variable show to 20, which will be used later to determine how many trends to display in the message. It then makes a request to the Twitter API to get a list of available locations for trends, and filters the list to find the location specified in the message. It then makes a request to the Twitter API to get the list of trends for that location, sorts the trends by tweet volume, and slices the list to get the top show number of trends. Finally, it creates an embed message with the sorted and sliced trend list and sends it to the Discord channel.
