    Plug 'kevinhwang91/rnvimr'

rnvmir.vim

" Make Ranger replace netrw and be the file explorer
let g:rnvimr_ex_enable = 1

nmap <space>r :RnvimrToggle<CR>

rc.conf

set preview_images_method ueberzug

default_linemode devicons

set show_hidden true

so The problem is the rmvmir does not show hidden file not as i configure it at the rc.conf but everything else does work like the buffer for the rmvimr shows up when i toggle it

Steps to reproduce the behavior:

:RvimrToggle
</(space)>R

Expected behavior A clear and concise description of what you expected to happen.

Show hidden file, the same ass the ranger command

Screenshots If applicable, add screenshots to help explain your problem. From ranger command on terminal

From :RmvmirToggle inside nvim

Additional context Add any other context about the problem here. i already have python 3 installed on my machine. perhaps i have to configure it?
