inlay hints don't work for golang in neovim?

i have hints working for lua, but not for go.
i've already tried a bunch of stuff like several go configs, though it seems like it is a server problem, because Settings: {} is what i get in healthcheck (so they basically shouldn't be empty, should they?).

syntax autocompletion works fine, "go to declaration" works too.

init.lua:

local capabilities = require('blink.cmp').get_lsp_capabilities()
      capabilities.textDocument = capabilities.textDocument or {}
      capabilities.textDocument.inlayHint = { dynamicRegistration = false }

      local servers = {
        clangd = {},
        gopls = {
          cmd = { 'gopls' },
          filetypes = { 'go', 'gomod', 'gowork', 'gotmpl' },
          settings = {

            gopls = {
              completeUnimported = true,
              usePlaceholders = true,
              analyses = {
                unusedparams = true,
              },
            },
          },
        },
        pyright = {},
        ts_ls = {},

        lua_ls = {
          -- cmd = { ... },
          -- filetypes = { ... },
          -- capabilities = {},
          settings = {
            Lua = {
              completion = {
                callSnippet = 'Replace',
              },
             
            },
          },
        },
      }

     
      local ensure_installed = vim.tbl_keys(servers or {})
      vim.list_extend(ensure_installed, {
        'stylua', -- Used to format Lua code
      })
      require('mason-tool-installer').setup { ensure_installed = ensure_installed }

      require('mason-lspconfig').setup {
        ensure_installed = {}, 
        automatic_installation = false,
        handlers = {
          function(server_name)
            local server = servers[server_name] or {}
            
            server.capabilities = vim.tbl_deep_extend('force', {}, capabilities, server.capabilities or {})
            require('lspconfig')[server_name].setup(server)
          end,
        },
      }
    end,

i have tried the following configs for gopls, none of them worked:

gopls = {
          settings = {
            gopls = {
              hints = {
                assignVariableTypes = true,
                compositeLiteralFields = true,
                compositeLiteralTypes = true,
                constantValues = true,
                functionTypeParameters = true,
                parameterNames = true,
                rangeVariableTypes = true,
              },
              completeUnimported = true,
              usePlaceholders = true,
              analyses = {
                unusedparams = true,
              },
            },
          },
        },

gopls = {
              ['ui.inlayhint.hints'] = {
                compositeLiteralFields = true,
                constantValues = true,
                parameterNames = true,
              },
            },

also tried to use plagin, but didn't help either: MysticalDevil/inlay-hints.nvim

also found the go hints definition, but i don't know how do i use this info (also there's an inlay_hint.go):
https://pkg.go.dev/golang.org/x/tools/gopls

please help understand why i can't get inlay hints in neovim for go and how to fix it
