For vim-tmux-navigator compatibility, use the vimTmuxNavigatorKeybinds prop during setup.
use {
    'Lilja/zellij.nvim',
    -- If you want to configure the plugin
    --[[
    config = function()
        require('zellij').setup({})
    end
    ]]
}{
    -- keys with designated default values.
    path = "zellij", -- Zellij binary path
    replaceVimWindowNavigationKeybinds = false, -- Will set keybinds like <C-w>h to left
    vimTmuxNavigatorKeybinds = false, -- Will set keybinds like <C-h> to left
    debug = false, -- Will log things to /tmp/zellij.nvim
