What is the MessageActionRow with djs v14?

const row = new MessageActionRow()
                .addComponents(
                    new MessageButton()
                        .setLabel('Erin\'s Support Server')
                        .setStyle('LINK')
                        .setURL('https://discord.gg/tT3VEW8AYF'),
                    new MessageButton()
                        .setLabel('Fill out this form!')
                        .setStyle('LINK')
                        .setURL('https://codinghelp.site')
                )
