Randomize Users in a Voice Channel (discord.js v12)

I am trying to randomize users into two teams, team 1 and team 2. However, in some scenarios it repeats the same user on both teams.

For example:

Team 1: User 1

Team 2: User 1

• The same user would be present on both teams instead of the other users' in the voice channel.

Is there a way to not present the same user twice or just once on one team.

try {
 
let users = message.member.voice.channel.members.map(member => `<@${member.user.id}>`)
                       
                        let team1 = users.sort(() => Math.random() - 0.5).slice(0, Math.floor(users.length / 2))
                        let team2 = users.sort(() => Math.random() - 0.5).slice(Math.floor(users.length / 2))
    
                        
                        const embed = new MessageEmbed()
                            .setTitle("Teams Created")
                            .setDescription(`Team 1: ${team1.join(', ')}\nTeam 2: ${team2.join(', ')}`)
                            .setColor("#36393E")
                            .setTimestamp()
                 
                        message.channel.send(embed)
                       
    
    
                    } catch (error) {
                        console.log(error)
                        const errorembed = new MessageEmbed()
                            .setTitle("⚙️ Error")
                            .setDescription(`An error has occured. Please try again`)
                            .setColor("#36393E")
                            .setFooter("If this error has occured multiple times, please contact the developer.")
                            .setTimestamp()
                        await message.channel.send("There was an error. Please try again.")
                    }
