My bot sends the message if someone boosts/unboosts the server.

You can see my code here:

client.on("guildMemberUpdate", (oldMember, newMember) => {
  const oldStatus = oldMember.premiumSince;
  const newStatus = newMember.premiumSince;

  if (!oldStatus && newStatus) {
    client.channels.cache
        .get("channel id")
        .send(`Thank you ${newMember.user.tag} (:`);
  }

  if (oldStatus && !newStatus) {
    client.channels.cache
        .get("channel id")
        .send(`woah ${newMember.user.tag}, unboost this server`);
  }
});

The code works perfectly, there is no error, but the bot is not tagging people, just mentioning the tag name like this:

I want the bot to mention people like this instead:

I think the problem is ${newMember.user.tag}. Usually, I use <@${member.id}>, but I don't know how to fix this code if using {user.tag}.
