Toggle fzf.vim if already open

Question

I am trying to write a vim function to toggle the fzf window if it is already open using fzf.vim.

The use case is if I am in the :Buffers view and I want to change to the :Files view if I try to execute :Files before closing :Buffers then fzf.vim complains.

The code is as below:

function FzfRunning()
    let buffers = filter(range(1, bufnr('$')), 'bufname(v:val) =~# ";#FZF"')
    for i in buffers
        " Delete buffer by ID
        execute "bw!" . i
    endfor
endfunction

command! -nargs=* ToggleFiles call FzfRunning| Files
command! -nargs=* ToggleBuffers call FzfRunning| Buffers

This works except for the fact that the fzf buffer loses focus. I would like it to focus the fzf buffer when ToggleFiles or ToggleBuffers is called.

I solved this problem with adding sleep

function FzfRunning()
  let buffers = filter(range(1, bufnr('$')), 'bufname(v:val) =~# ";#FZF"')
  for i in buffers
    " Delete buffer by ID
    execute 'bw! ' . i
  endfor
  " we need to sleep here so fzf will be focused properly
  sleep 10m
endfunction
