How do we switch between single or multiple selections after TomSelect instance has been instantiated?

[samnang]

On page load, we create a new TomSelect instance with new TomSelect('#select-value'). The user's operator selection determines if the input can accept one or multiple values.

I have the logic to switch between single or multiple on the value select input like this:

if (
  operatorElement.value === "in" ||
  operatorElement.value === "not_in"
) {
  valueElement.multiple = "true"
} else {
  valueElement.multiple = undefined
}

const tomSelect = valueElement.tomselect
// how can we refresh or re-initialize the TomSelect instance to reflect base on the updated select input?
