	...e/nvim/lazy/pommodoro-clock.nvim/lua/pommodoro-clock.lua:233: in function <...e/nvim/lazy/pommodoro-clock.nvim/lua/pommodoro-clock.lua:232>

To reproduce:

1. run require('pommodoro-clock').start(some_key).
2. run require('pommodoro-clock').close().
3. create a vsplit.

I believe that you should remove this autocmd after it's close()d.
