How to make randombones transparent?

[artkpv]

Hello, thank you for this great colorscheme!

How to make it transparent? In my config (see it here):

      vim.g.randombones = { transparent_background = true }
      vim.o.background = 'dark'
      vim.cmd.colorscheme 'randombones'

I start nvim as:

   kitty ~/bin/start

where ~/bin/start contains:

 nvim -c 'cd ~/mydir/notes' -c WikiEnable  -c 'lua vim.g.init_my_wiki_config()'

And my kitty config has:

background_opacity 0.95

However the background is not transparent:

Hi there! I can replicate the problem just with randombones, but the rest of the colorschemes are working fine.
Unfortunately I don't have much capacity to investigate further right now.
