How to make vim.snippet work with vim.lsp.omnifunc completion?

1

Neovim 0.11 should have built-in basic snippet support with vim.snippet module.

Can I make it work for code completion expansion of built-in vim.lsp.omnifunc? To be more specific, I need to set it up for Golang’s gopls Language server function arguments placeholders expansion:

-- from my nvim's init.lua
vim.lsp.config['gopls'] = {
  cmd = { 'gopls' },
  filetypes = { 'go', 'gomod', 'gowork', 'gotmpl' },
  root_markers = { 'go.work', 'go.mod', '.git' },
  settings = {
    gopls = {
      usePlaceholders = true,
    }
  },
}

vim.lsp.enable('gopls')

With usePlaceholders option, completion from LSP server should also return snippet for function arguments (as placeholders). I know it works, on the same machine with Emacs + Eglot LSP client. And with the same gopls and project testing on, of course.

Any idea how to make it work, besides to rely on 3rd party plugins like LuaSnip?
