How do I get defineExpose exported data in slot in vue3 setup syntax？

[alamhubb]

on option api, i can type.data() get data

useSlots().default()[0].type.data()[var]

and How do we do that in the setup syntax

useSlots().default()[0].xxxx?

What should I replace the code in xxxx?

The code for my interface is dynamically rendered and does not have a render slot, so I cannot use ref() for the slot.

<template>
  <div ref="goldenLayoutContainer" id="goldenLayoutContainer" style="width: 100%; height: 100%;">
    <template v-for="(element, index) in glRenderElements">
      <teleport :to="element.data.elmId">
        <component :is="element.element"></component>
        <!--            {{ element.element }}-->
      </teleport>
    </template>
  </div>
</template>

js

onMounted(() => {
  glRenderElements.value = []

  const config: LayoutConfig = reactive({})

  const slots = useSlots()

  if (slots.default) {
const defaults = slots.default()
const defaultChild = defaults[0]

// What do I do if I want to get the defineExpose exported data in the defaultChild slot

}
