I am trying to trigger a new random number every 30 seconds of every minute. I have kind of working. It fires once. How do I rearm my promise after it fires, so it can fire again in 30 seconds?

    let token = new Promise((resolve, reject) => {
      let id = setInterval(function() {
        let sec = new Date().getSeconds()
        if ( sec === 0 || sec === 30 ) {
            setInterval(getToken, 30000);
            getToken();        
            clearInterval(id);
        }
      },1000);

      function getToken(){
        token = Math.random()
        resolve(token)
      }
    })

    console.log(await token)
