Autocompletion not working for html

[Leo-Zarni01]

Hello, so I have installed vscode language server according to the guide shown in this page: https://github.com/neovim/nvim-lspconfig/blob/master/doc/server_configurations.md#html.

However, it seems that even though the language server is installed and is working, the autocomplete feature seems to be not working. I have followed the instructions on that page and even enabled the snippet (LuaSnippet) but nothing shows up in autocompletion.

Here are the images below for your reference:

Looking forward for your help, thank you!
