Passing initialization options (user preferences) to Language Server through LanguageServerProvider

[pospisilf]

Hi, I am trying to build Language Client using LanguageServerProvider and I have only one problem - I am wondering how I can pass initialization options to Language Server. Eclipse has function getInitializationOptions() from org.eclipse.lsp4e.server package. VSCode has clientOptions inside LanguageClient from vscode-languageclient/node. Is there some way, how can I pass these options to my server? I am hopelessly lost. Thanks.
