  .addFields({ name: 'Coins', value: '100', inline: true });

await interaction.reply({ embeds: [embed] });

Button row example

const { ActionRowBuilder, ButtonBuilder, ButtonStyle } = require('discord.js');

const row = new ActionRowBuilder().addComponents(
  new ButtonBuilder()
    .setCustomId('yes')
    .setLabel('Yes')
    .setStyle(ButtonStyle.Success),
  new ButtonBuilder()
    .setCustomId('no')
    .setLabel('No')
    .setStyle(ButtonStyle.Danger),

await interaction.reply({ content: 'Confirm?', components: [row] });
