hi , i used blink.cmp and ellisonleao/gruvbox.nvim theme in neovim . when used blink, i always want to change the cmp menu background color , let it same to the blink documention color. but i dont know how to work.

bellow is part of my blink config and screen shot. tks.

config: menu = { scrolloff = 1, scrollbar = false, draw = { columns = { { 'kind_icon' }, { 'label', 'label_description', gap = 1 }, { 'kind' }, { 'source_name' }, }, treesitter = { 'lsp' }, }, }, documentation = { window = { scrollbar = false, winhighlight = 'Normal:BlinkCmpDoc,FloatBorder:BlinkCmpDocBorder,EndOfBuffer:BlinkCmpDoc', }, auto_show = true, treesitter_highlighting = true, },

i got it by adding ' winhighlight = 'Normal:BlinkCmpDoc,FloatBorder:BlinkCmpDocBorder,CursorLine:BlinkCmpMenuSelection,Search:None', '.
this feels a bit strange. why are there different color options between ' BlinkCmpMenu ' and 'BlinkCmpDoc ' in same theme. i think same color is better.

completion = { keyword = { range = 'full' }, list = { selection = { preselect = false, auto_insert = true } }, ghost_text = { enabled = true }, menu = { winhighlight = 'Normal:BlinkCmpDoc,FloatBorder:BlinkCmpDocBorder,CursorLine:BlinkCmpMenuSelection,Search:None', scrolloff = 1, scrollbar = false, draw = { columns = { { 'kind_icon' }, { 'label', 'label_description', gap = 1 }, { 'kind' }, { 'source_name' }, }, treesitter = { 'lsp' }, }, }, documentation = { window = { scrollbar = false, winhighlight = 'Normal:BlinkCmpDoc,FloatBorder:BlinkCmpDocBorder,EndOfBuffer:BlinkCmpDoc', }, auto_show = true, treesitter_highlighting = true, }, },
