How would it be possible to use beforeDestroy in vue function api

Hi devs,

I want to know how it is possible to use beforeDestroy in the setup () component.
I need to delete some data when I leave a particular section.

When I define beforeDestroy() as:
It shows me an error that I cannot use beforeDestroy within the setup() component.
If there is an equivalent to beforeDestroy() and can you tell me or help how to make it work, I will appreciate it.

<script>
  import {value , onCreated, watch} from 'vue-function-api';
 
  export default{
    name: "Section",
    setup(){
      beforeDestroy(){
        
      }
      return{
      }
    }
  };
</script>

  import {value , onCreated, watch} from 'vue-function-api';
 
  export default{
    name: "Section",
    setup(){
      beforeDestroy(() => {
          // do something 
     })
      return{
      }
    }
  };
