 If you used [vim-plug](https://github.com/junegunn/vim-plug) to install the LSP plugin, then you need to use the VimEnter autocmd to initialize the LSP server and to set the LSP server options.  For example:
 ```viml
+let lspOpts = #{autoHighlightDiags: v:true}
+autocmd VimEnter * call LspOptionsSet(lspOpts)
+
 let lspServers = [#{
 	\	  name: 'clang',
 	\	  filetype: ['c', 'cpp'],
 	\	  path: '/usr/local/bin/clangd',
 	\	  args: ['--background-index']
