title: discord.js v13 | can't get targeted user's infos
body: <p>i'm using discord.js version <strong>13.1.0</strong> with node.js version <strong>16.7.0</strong>, i writed this code to show me user's info in a embed, but the problem is it only shows me my infos.</p>
  <p>I tried also this <code>guildMember.user</code> instead of <code>user</code> but it can't execute the command it shows me in the console <code>TypeError: Cannot read property 'user' of undefined</code>.</p>
  <p>Here's the command's code:</p>
  <pre><code>module.exports = {
      data: new SlashCommandBuilder()
          .setName('info')
          .setDescription('Get info about a user or a server!')
          .addSubcommand(subcommand =&gt;
              subcommand
                  .setName('user')
                  .setDescription('Info about a user')
                  .addUserOption(option =&gt; option.setName('target').setDescription('The user'))),
      async userInfo = new MessageEmbed()
                  .setColor('#0099ff')
                  .setTitle('Some title')
                  .setAuthor('Some name', interaction.user.displayAvatarURL({ dynamic: true }))
                  .setDescription('Some description here')
                  .setThumbnail(interaction.user.displayAvatarURL({ dynamic: true }))
                  .addFields(
                      { name: 'Hello', value: 'Hello' },
                      { name: '\u200B', value: '\u200B' },
                      { name: 'ID', value: interaction.user.id, inline: true },
                      { name: 'Username', value: interaction.user.tag, inline: true },
                  )
                  .setTimestamp()
                  .setFooter('Some footer text here', 'https://i.imgur.com/AfFp7pu.png');
      if (interaction.options.getSubcommand() === 'user') {
              const user = interaction.options.getUser('target');
              if (user) {
              await interaction.reply({ embeds: [userInfo] });
     };
  };
