How to configure "LSP server configuration schema"?

[fritzrehde]

Hi, I'm very new to neovim LSP and mason. I am using nvim-cmp, mason.nvim, mason-lspconfig.nvim and nvim-lspconfig.
When calling :Mason in neovim, I see all available and installed LSPs, and when clicking on one I see some config options. I want to configure some of the options in "LSP server configuration schema", but have absolutely no clue how to do that? Do I do this with Mason, nvim lsp or the LS itself (how though?)?
Thanks!

Hey! So what's presented in the :Mason window is a read-only overview of what settings the server has defined in its schema. How you modify these settings depend on how you set up your servers. With lspconfig it's done via the settings table during setup (:h lspconfig-setup), for example like so:

require("lspconfig").pyright.setup {
    settings = {
        pyright = {
            disableLanguageServices = true,
            disableOrganizeImports  = true,
        }
    }
}

Would it be possible to have this integrated in :Mason? Would be really cool if I could press e for example and edit the values. My use case is that I want to edit the feature-flags used by rust-analyzer quickly.
