Using a Backdrop 
The backdrop property is a boolean that represents whether the backdrop should be displayed or not. The backdrop is a semi-transparent overlay that covers the entire screen, except for the highlighted element.
Using the backdrop prop 
To enable the backdrop, you can use the backdrop prop in the VTour component.
vue
<script setup lang='ts'>
  // ...
  const steps = [...];
</script>
<template>
  <VTour :steps="steps" autoStart highlight/> // [!code --]
  <VTour :steps="steps" autoStart backdrop/> // [!code ++]
  ...
</template>Click "Done" to close the Tooltip
INFO
By default, the backdrop is disabled.
