Cannot enable diagnostic highlight & virtual text on NeoVim

Hi, I'm trying to get the highlight and virtual text of warning & error like VSCode on Neovim but currently I still stuck on how to enable them.

In Neovim, I cannot see any warning or error highlight Screen Shot 2022-07-21 at 19 52 49

However in VSCode I can see and check the warning quite easily. Screen Shot 2022-07-21 at 19 53 34
