How to use Vue ref value assigned in a useQuery as the enabled option in another useQuery?

vue script setup includes (psuedo code): 
const var = ref<string>("")
useQuery function that is passed var and assignes value to var.value
useQuery function that is passed var and has enabled option of var.value !== ""
const var = ref<string>("")
useQuery function that is passed var and assignes value to var.value
useQuery function that is passed var and has enabled option of var.value !== ""
The second useQuery function runs without the enabled option, but it runs twice (first time is invalid since var is an empty string). However when I add the enabled option it never runs, even though var value is updated by the first useQuery function

Hi, you are probably make the classic mistake of unwrapping the value prematurely or computing the value for enabled without reactivity in place. This way enabled will get a value computed just for initial render. You need to use computed, ref or reactive and pass that to enabled without unwrapping. Ex. 
const isEnabled = ref(false)

const onButtonCLick = () => {
  isEnabled.value = true;
}

useQuery({
  enabled: isEnabled
})
const isEnabled = ref(false)

const onButtonCLick = () => {
  isEnabled.value = true;
}

useQuery({
  enabled: isEnabled
})
