I implement searching/filtering within v-autocomplete with multiple selection and select all. Currently select all will select all from the list which include filtered/un-filtered (screenshot: 67 item(s) selected although it has been filtered to 4). I need that select all to just select those 4 items (yellow box).
Question is how do I get/access the v-autocomplete's filtered items?
Saw a post which asked almost same question as mine, but no answer from 2019. Someone mentioned to use
this.$refs.autoCompleteRef.filteredItems
But its not working.

It works exactly as mentioned.
See the playground. It's better to check it in full-page mode.
