How to send a request directly to the language server set up by coc.nvim

[uga-rosa]

I would like to send a request like textDocument/references directly from the vim script and receive the resulting Location[].
If you know neovim's built-in lsp client, interpret this as wanting to do something like vim.lsp.buf_request_sync().

:h CocAction('references').

I would like to touch a lower layer. The current cursor position is useless since it is for use in the fuzzy finder. I would like to use all the parameters that I have created to send to LS. Is there a way?
Would it make sense if I say I want to access textDocument/references, not references?

They were same, references did ReferencesRequest.

Use :h CocRequest(), with langserver id, textDocument/references, and custom position params.

Also :h CocRequestAsync() for async requests.

Thanks!

Can I get a list of the langserver ids that are enabled for a given buffer?

[fannheyward]

:CocList services, this lists all activated services, not current buffer only.
