How can I disable kicking members who have a higher role?

Question

So I'm currently creating a kick command and I ran into a problem:

All members are able to kick other members, even if they have a higher role, eg a "normal" user can kick a admin or mod . But I want the bot to return a message like

"You can't kick members with equal or higher roles!"

This is my current code:

const { MessageEmbed, User } = require('discord.js');
const config = require('../../configs/config.json');

module.exports = {
    config: {
        name: "kick",
    },
    run: async (client, message, args) => {
        if (!message.member.hasPermission('KICK_MEMBERS', 'ADMINISTRATOR')) {
            return message.channel.send({
                embed: {
                    title: 'You are unable to kick members',
                    color: config.embedcolor
                }
            })
        }
        if (!args[0]) {
            return message.channel.send({
                embed: {
                    title: 'PLease mention a user',
                    color: config.embedcolor
                }
            })
        }
        if (message.member.permissions.has("MANAGE-MESSAGES", "ADMINISTRATOR"))
            return message.channel.send({
                embed: {
                    title: "I can't kick staff members!",
                    color: config.embedcolor
                }
            })

        const member = message.mentions.members.first() || message.guild.members.cache.get(args[0]);

        try {
            await member.kick();
            await message.channel.send({
                embed: {
                    title: `${member} has been kicked!`,
                    color: config.embedcolor
                }
            })
        } catch (e) {
            return message.channel.send({
                embed: {
                    title: `User isn't in this server!`,
                    color: config.embedcolor
                }
            })
        }

    }
}

Try this method:

if(message.member.roles.highest.comparePositionTo(message.mentions.members.first().roles.highest) > 0){
    //member has higher role then first mentioned member
    if(member.kickable){  //Just in case
        message.mentions.members.first().kick();
    }
}else{
    message.reply("You can't kick your senpai °^°");
}

Edit: In latest discord.js version highestRole has been replaced with roles.highest
