How to make a teleport GUI using a mod call?

I made this mod call script which sends a complaint, the player's name and user id, and the server ID to discord. Here's that script:

local webhookURL = "This is not the real webhook, but I just didn't want people using that webhook." -- Enter webhook ID


local filteringFunction = game.ReplicatedStorage.FilteringFunction
local Players = game:GetService("Players")



local HttpService = game:GetService("HttpService")

function filteringFunction.OnServerInvoke(player, msg)
    local thumbnail = Players:GetUserThumbnailAsync(player.UserId, Enum.ThumbnailType.AvatarBust, Enum.ThumbnailSize.Size420x420)

    if game.JobId == "" then
        serverId = "N/A"
    else
        serverId = tostring(game.JobId)
    end

    local data = 
    {
        ["content"] = "",
        ["embeds"] = {{
            ["title"] = "",
            ["type"] = "rich",
            ["color"] = tonumber(0xFF0000),
            ["thumbnail"] =  {
                ["url"] =  tostring(thumbnail)
            },
            ["fields"] = {
                {
                    ["name"] = "**Player**",
                    ["value"] = string.format("%s | %s", player.Name, player.UserId)    
                },
                {
                    ["name"] = "**Complaint**",
                    ["value"] = msg
                },
                {
                    ["name"] = "**Server ID**",
                    ["value"] = serverId,
                }
            }

        }}
    }

    local jsonData = HttpService:JSONEncode(data)

    HttpService:PostAsync(webhookURL, jsonData)
    return ""
end

Here's the result: https://prnt.sc/tnj5om

I want the mods to be able to teleport to their server and assist them. Can anyone tell me how to do this? Here's also the GUI I have: https://prnt.sc/tnj7ks

I made this script, but it didn't work, can some help?

(The script.)

local TeleportService = game:GetService("TeleportService")
local Button = script.Parent.Submit
local ServerId = script.Parent.ServerId.Text
local PlaceId = 5368128309
local Player = game.Players.LocalPlayer


Button.MouseButton1Click:Connect(function()
	TeleportService:TeleportToPlaceInstance(PlaceId, Player, ServerId)
end)
