Diagnostics Disabled flag seems do not work

[LLMChild]

nvim-tree.lua/lua/nvim-tree/diagnostics.lua

Line 44 in 26632f4

is_disabled = vim.diagnostic.is_disabled()

I am trying to write a keybind to turn off diagnostics.

vim.g.diagnostics_active = true
function _G.toggle_diagnostics()
if vim.g.diagnostics_active then
  vim.g.diagnostics_active = false
  vim.diagnostic.hide()
  vim.lsp.handlers["textDocument/publishDiagnostics"] = function() end
  vim.notify("Diagnostics are now off", vim.log.levels.INFO, { title = "Diagnostics" })
else
  vim.g.diagnostics_active = true
  vim.lsp.handlers["textDocument/publishDiagnostics"] = vim.lsp.with(
    vim.lsp.diagnostic.on_publish_diagnostics, {
      virtual_text = false,
      signs = true,
      underline = true,
      update_in_insert = true,
    }
  )
  vim.notify("Diagnostics are now no", vim.log.levels.INFO, { title = "Diagnostics" })
end
end
map('n', '<leader>td', ':call v:lua.toggle_diagnostics()<CR>',  {noremap = true, silent = true, desc = "Toggle Diagnostics"})

This works for my diagnostics all buffers but does not work for nvim-tree.
So I am trying to find a function which can toggle Diagnostics for nvim-tree in runtime.
Sadly, nvim-tree does not have anything like this.
So I checked the code , and I found this flag.
Then I add enable and enable(false) in my keybindings.
like this

function _G.toggle_diagnostics()
if vim.g.diagnostics_active then
  vim.g.diagnostics_active = false
  vim.diagnostic.hide()
  vim.diagnostic.enable(false)
  vim.lsp.handlers["textDocument/publishDiagnostics"] = function() end
  vim.notify("Diagnostics are now off", vim.log.levels.INFO, { title = "Diagnostics" })
else
  vim.g.diagnostics_active = true
  vim.diagnostic.enable()
  vim.lsp.handlers["textDocument/publishDiagnostics"] = vim.lsp.with(
    vim.lsp.diagnostic.on_publish_diagnostics, {
      virtual_text = false,
      signs = true,
      underline = true,
      update_in_insert = true,
    }
  )

It didn't not work either, and I checked status using :lua print(vim.diagnostic.is_disabled()).
But nvim-tree still won't hide the diagnostic.
Can anybody in this community help me?
