how to make background transparency in alacritty

[WingDust]

I already write

vim.cmd([[
func! s:transparent_background()
    highlight Normal guibg=None ctermbg=None
    highlight NonText guibg=None ctermbg=None
endf
autocmd ColorScheme * call s:transparent_background()
]]
)

in chadrc.lua
with follow alacritty/alacritty#1082,
but no effect

[siduck]

pls use the chadrc option :<

[searleser97]

could you clarify ? or be more explicit on your answer ? I do not know anything about the chadrc option, Where can I find info about it ?

[siduck]

@searleser97 there's already a transparency option, please read core/default_config.lua
