'I'm getting "mention not defined" error when trying to pass v12 code to v13

I'm trying to pass a code from v12 to v13 and I get "mention not defined" error. I think it might be in that part bellow. Could someone tell me if this is on v13?

message.channel.send({content: `${mention === "@everyone" ? "`@everyone`" : `${mention === undefined ? '' : '`@' +mention.name+ '`'}`}`, embeds: [previewEmbed] }).then(delMsg => {
          setTimeout(() => {
            delMsg.delete()
          }, 60000)
        })


      })

  })
