How to display more of the documentation for system libraries?

Hi I'm new to LSPs so not sure where exactly to ask this question.

I'm trying to get kotlin LSP to show more of the documentation like how Intellij does, any pointers on how can I go about doing that?

Currently using it in neovim with it's native LSP + kotling-language-server but I don't see the complete doc like shown above.

Current config:

    ◍ kotlin_language_server 
      version     1.3.1                                          
      installed   21 Jul 2022 18:45                              
      install dir ~/.local/share/nvim/lsp_servers/kotlin         
      homepage    https://github.com/fwcd/kotlin-language-server 
      
      ↓ Server configuration schema (press enter to collapse)
        This is a read-only representation of the settings this server accepts. Note that some settings might not apply to neovim.
        For information on how to customize these settings, see :help lspconfig-setup

        → kotlin.languageServer.enabled                  default: true
        → kotlin.languageServer.path                     default: ""
        → kotlin.languageServer.port                     default: 0
        → kotlin.languageServer.transport                default: "stdio"
        → kotlin.linting.debounceTime                    default: 250
        → kotlin.snippetsEnabled                         default: true
        ↓ kotlin.trace.server                            default: "off"

Start by inspecting the kotlin_language_server entry point for LSP documentation responses and Neovim's native LSP handling of them. Compare the current output with the IntelliJ example; done means system-library documentation is displayed as completely as in the example.
