How to set up a background image

[JATIN-RAGHAV]

How can I set up a backgroun image.
Either I can make the background transparent and make the default terminal backgroun image appear. That works.
But how can I use an image as background for my nvim instead of making the bg transparent, which will appear even when I have opened a floating gui like Lazy??

use an image as background for my nvim instead of making the bg transparent is simply impossible only through Neovim, nor the matter of catppuccin/nvim, please check the document of the terminal you use.
