how to make a discord invitation bot,

class Events {
    constructor() {
        this.name = Event.InviteCreate
    }
    async execute(invite) {
        const newInvite = new Invite({
            CreateInv: invite.inviter.id,
            GuildID: invite.guild.id,
            InviteCode: invite.code
        });
        await newInvite.save();
    }
}
module.exports = Events

const client = Underline.Thealoq
const { Events: Event, EmbedBuilder } = require("discord.js")
const Discord = require("discord.js")
const Invite = Underline.Model.Invite
const Modal = Underline.Model.GuildSettings
const Message = require("../../../Variables/variables")
class Events {
    constructor() {
        this.name = Event.GuildMemberAdd
    }
    async execute(member) {

        let Settings = await Modal.findOne({ GuildID: member.guild.id })
        if(!Settings) return
        if(!Settings.Status) return
        let channel = client.channels.cache.get(Settings.InvCh)
        if (!channel) return 
        
        const invites = await Invite.find({ GuildID: member.guild.id });
        if (!invites) return;
    
        const usedInvite = invites.find(invite => invite.Point < invite.Point + 1);
        if (!usedInvite) return;
    
        const InvMember = await member.guild.members.fetch(usedInvite.CreateInv);
        usedInvite.UseMember.push(member.id);
        usedInvite.Point++;
        await usedInvite.save();
        const content = Message.InvAdd(member,InvMember,usedInvite)
        const embed = new EmbedBuilder()
        .setColor(Discord.Colors.Green)
        await channel.send({ embeds :[embed.setDescription(content)]});
