UltiSnips integration for completion with arguments placeholders?

[torimus]

What configuration is required for vim-lsp to have item completion including insertion of possible arguments as snippet placeholders?

For example, I have registered pylsp server for Python buffers with vim-lsp.
When I try to complete re.sea symbol with omnifunc, single match is offered

re.search(pattern, string, flags) function

however after i confirm this completion, only the name without arguments is inserted

re.search

Is there an option how to insert possible arguments as well? Similar like vim-go plugin which uses UltiSnips for this goal? To have inserted following instead, with arguments as UltiSnips placeholders:

re.search(<pattern>, <string>, <flags>)

I have all ultisnips, vim-lsp-snippets and vim-lsp-ultisnips installed.
Underlying pylsp server has enabled completion with parameters (pylsp.plugins.jedi_completion.include_params is true).

Any clue?
