How can bots ping someone after a member gets a role? Discord js v12

So i want the bot ping someone, after member get some role

this is my code

client.on('guildMemberUpdate', async(member) => {
    const memberRole = message.guild.roles.cache.find((role) => role.id ==='role id');//and this is for the role id, so the bot knows this role and the bot automatically pings someone to the channel i want

const Channel = member.guild.channels.cache.get('channel id') //and this channel id, i want the bot ping someone in this channel
    Channel.send(`here lmao <@${member.id}> `)
    .then((member)=> member.delete({
        timeout: 10000 //and this i purposely made this to look like a ghost ping
    }));
})

I know this code looks messy (: , so i’m asking for your help
Thank u!
