Discord bot : random images in an embed message

I’m beginning programming a discord bot, and I did my first command which is to hug another member. The answer is along with an anime hug gif. But now, what I would like to do is, instead of only setting one gif, to put on some others which would be selected randomly. However, I don’t know how to proceed to a random gif.

const Discord = require("discord.js");
const { UserAgent } = require("discord.js/src/util/Constants");
const ytdl = require("ytdl-core");
const Client = new Discord.Client({
    intents : [
        Discord.Intents.FLAGS.GUILDS,
        Discord.Intents.FLAGS.GUILD_MESSAGES
    ]
});

const prefix ="<";

Client.on("ready", () => {
    console.log("bot opérationnel")

});

Client.on("message", message => {
    if (message.author.bot) return;
    if (message.content.startsWith (prefix + "hug")){
        let mention = message.mentions.members.first();

        if(mention === undefined){
            message.channel.send("u have to hug someone who actually exists");
        }
        else {
            const embed = new Discord.MessageEmbed()
            .setColor("DARK_RED")
            .setTitle(":hugging: " + mention.displayName + " recieved a hug from " + message.author.username + " !")
            .setImage("gif.gif");

        message.channel.send({embeds: });
        }
    }
});

Client.login("token");

>Solution :

So this would be selecting a random element from an array of gifs,

const hugs = ['gif1.gif', 'gif2.gif'];

const randomHug = hugs[Math.floor(Math.random() * hugs.length)];

You would then of course use the variable randomHug as the gif. .setImage(randomHug);
