VSCode like multi select

I would like to have VSCode like multi select experience.
for example if I hit Ctrl-D, it will select the current word first, and the cursor position is still at the current word. then If I hit ctrl-d again, it will go to the next matched word and select it, the cursor position is at that next matched word

I tried with coc multi cursor and this is the code I have so far:

hi CocCursorRange guibg=#b16286 guifg=#ebdbb2
nmap <silent> <C-d> :call <SID>multi_select_word()<CR>

func! s:multi_select_word()
  if !get(b:, 'cursor_selected', 0)
    let b:cursor_selected = 1
    exec "norm \<Plug>(coc-cursors-word)"
  else
    exec "norm *\<Plug>(coc-cursors-word)"
  endif
endfunc

The only missing piece is a way to reset b:cursor_selected = 0 when I cancel the multi select. It can be an autocmd event, or override <ESC> mapping from coc (not ideal), or directly check the multi cursor is activated from coc like if coc#utils$is_multi_cursors_activated()

is there another way? Am I missing something?
