SetTimeout or SetInterval Support?

[Aduviel]

I have several datapoints I would like to show via a single custom_field.

Is some variation of the following example possible?

custom_fields:
    status: |
    [[[
      function test() {
        if (variables.idx > 2) {
          variables.idx = 0 
        } else { 
          variables.idx++ 
        }
      }
      setInterval(test, 7000);
      return `<div
        style="font-size: 14px; 
        font-weight: bold;
        color: black;
        ">${variables.arr[variables.idx]}</div>`
    ]]]

The button card using the status field displays without errors, but the variable is not incrementing every 7 seconds.
