Discord.js How to display participants on the server?

Question

JavaScript

client.on("message", message => {

    if(message.content == `${prefix}staff-list`) {
        const ListEmbed = new Discord.MessageEmbed()
            .setTitle('Users with the staff role:')
            .setDescription(message.guild.roles.cache.find('729044882903007314').members.map(m=>m.user.tag).join('\n'));
        message.channel.send(ListEmbed);

Unfortunately it doesn't work. Console throws an error : TypeError: fn is not a function

Answer 1

replace

message.guild.roles.cache.find('729044882903007314').members.map(m=>m.user.tag).join('\n'));

on the

message.guild.roles.cache.get('729044882903007314').members.map(m=>m.user.tag).join('\n'));
