let g:fzf_buffers_jump = 1 option doesn't work

First time trying fzf.vim. As stated in the title g:fzf_buffers_jump = 1 options doesn't seem to work.

I created a minimal config, it still doesn't work. Maybe I'm missing something here. I'm pretty new to this. Any assistance is greatly appreciated.

" My whole config

call plug#begin()

Plug 'junegunn/fzf', { 'do': { -> fzf#install() } }
Plug 'junegunn/fzf.vim'

call plug#end()

let g:fzf_buffers_jump = 1

[x] I have fzf 0.30.0 or above
[x] I have read through https://github.com/junegunn/fzf.vim/blob/master/README.md
[x] I have read through https://github.com/junegunn/fzf/blob/master/README-VIM.md
[x] I have read through the manual page of fzf (man fzf)
