I am trying to change button's current emoji to a new one like this:

// Initializing button
const row = new MessageActionRow()
    .addComponents(
        new MessageButton()
            .setCustomId('play_pause')
            .setEmoji('⏸')
            .setStyle('PRIMARY')
    )
// Button was sent to Discord
await message.channel.send({
                components: [row]
            });
// Changing content of a button
row.components[0].setEmoji('▶');

But in the Discord nothing changes. When I call console log, I get this:

MessageButton {
  type: 'BUTTON',
  label: null,
  customId: 'play_pause',
  style: 'PRIMARY',
  emoji: { animated: false, name: '▶', id: null },
  url: null,
  disabled: false
}

So as I get it, I need to resend the button for it to change. But can I somehow change the content without resending it?
