Webhook image help

I wanna make in webhook image like this:

local url = "https://discord.com/api/webhooks/_/_"

function rgbToColor(red, green, blue)
	return bit32.lshift(red, 16) + bit32.lshift(green, 8) + blue
end

local data = {
	["embeds"] = {
		{
			["title"] = "Nextinel1 Just Hatched A Secret 🎉",
			["description"] = "**King Doggy**",
			["url"] = "",
			["color"] = rgbToColor(143, 24, 212),
			["image"] = {
				['url'] = "",
			},
			["fields"] = {
				{
					["name"] = "🍀**Rarity**",
					["value"] = "1 in 2M",
					["inline"] = false
				},
				{
					["name"] = "🥚**Egg**",
					["value"] = "Basic Egg",
					["inline"] = false
				},
				{
					["name"] = "🥚**Eggs Opened**",
					["value"] = "1,488,228",
					["inline"] = false
				},
			}
		}
	}
}

local encodedBody = game:GetService("HttpService"):JSONEncode(data)
local response = game:GetService("HttpService"):RequestAsync(
	{
		Url = url,
		Method = "POST",
		Headers = {["Content-Type"] = "application/json"},
		Body = encodedBody
	}
)
