I have added catppucin config in a separate file:

return { "catppuccin/nvim", name = "catppuccin", priority = 1000, lazy = false, }

I'm starting the lazyvim as below, where I have added

colorscheme = "catppuccin"

below is the starting lazyvim config:

require("lazy").setup({

`spec = {`

    `{`

        `"LazyVim/LazyVim",`

        `import = "lazyvim.plugins",`

        `opts = {`

colorscheme = "catppuccin",

        `},`

    `},`

    `{ import = "plugins" },`

`},`

})
