I tried to migrate fomr packer.nvim to lazy.nvim and I encounter problem with deoplete. With packer is triggered on every document and .tex files. With Lazy.nvim is not.

I appreciate any help!

Here is my nvim tree:

 .
├──  init.lua
├──  lazy-lock.json
└──  lua
   └──  mafsi
      ├──  lazy.lua
      └──  plugins
         ├──  colorscheme.lua
         ├──  deoplete.lua
         └──  vimtex.lua

Here are my files:
