Can't expand snippets (neovim inside of powershell)

[JBic9832]

So I am using neovim inside of powershell and have gotten code snippets to appear properly but I am unable to expand them. I added the following to the snippet.vim file:

inoremap <silent><expr> <TAB>
      \ coc#pum#visible() ? coc#_select_confirm() :
      \ coc#expandableOrJumpable() ? "\<C-r>=coc#rpc#request('doKeymap', ['snippets-expand-jump',''])\<CR>" :
      \ CheckBackSpace() ? "\<TAB>" :
      \ coc#refresh()

function! CheckBackSpace() abort
  let col = col('.') - 1
  return !col || getline('.')[col - 1]  =~# '\s'
endfunction

let g:coc_snippet_next = '<tab>'

When I press tab it just tabs over and snippets dissapear. I dont know if its my config or powershell. Any help would be much appreciated.

Okay so now tab no longer tabs over but when in the snippets menu but it doesn't expand the snippets when i use

imap <C-l> <Plug>(coc-snippets-expand)

in coc.vim or snippet.vim

Don't know, you can debug it https://github.com/neoclide/coc.nvim/wiki/Debug-coc.nvim

With imap <C-l> <Plug>(coc-snippets-expand), you have to make sure it's called and you have trigger ahead of cursor.
