Whe can I add new "LuaSnip" snippets?

I have:

1 - nvim-cmp
2 - LuaSnip
3 - cmp_luasnip

I know LuaSnip uses json snippets format, but where can I add new ones. If it is hard I maybe will get back to ultisnips. But at least I am asking you guys to give me ideas. Thanks!

I already have found something that seems like a reference:
~/.local/share/nvim/site/pack/packer/start/LuaSnip/Examples/snippets.lua

require("luasnip/loaders/from_vscode").lazy_load({paths = "~/.config/nvim/snippets/"}) -- You can pass { paths = "./my-snippets/"} as well

Now more research gave me

    use {
        'L3MON4D3/LuaSnip',
        -- after = "nvim-cmp",
        wants = "friendly-snippets",
        -- after = "nvim-cmp",
        config = function()
            -- require'plugins.config.cmp'
            -- require("luasnip/loaders/from_vscode").load()
            require("luasnip/loaders/from_vscode").lazy_load({paths = "~/.config/nvim/snippets/"})
        end
    }

Caveat: I don’t use this plugin (yet)

It sounds like you can either assign the snippet (as a Lua object) directly to the snippets or autosnippets table, or put JSON snippets in a directory and use lazy_load({paths = '...'} as you discovered.

Both versions are shown the sample configuration:

-- Define some snippets
require("luasnip").snippets = {
  -- Snippets for all filetypes
  all = { ... }
  -- Snippets for filetype=python
  python = { ... }
}

-- Load snippets from JSON files (VSCode syntax)
require("luasnip/loaders/from_vscode").lazy_load({
  paths = {
    vim.fn.stdpath('config') .. '/snippets',
  }
})

You could also do something more sophisticated with the paths, like finding all snippets/*.json files anywhere in &runtimepath:

--[[ Split a string into lines. ]]
local function split_lines(txt)
  return vim.fn.split(txt, '\n')
end

--[[ Find files in the runtime path. ]]
local function glob_runtimepath(pattern)
  local runtime_path = vim.fn.escape(vim.o.runtimepath, ' ')
  local search_result = vim.fn.globpath(runtime_path, pattern)
  return split_lines(search_result)
end

require("luasnip/loaders/from_vscode").lazy_load({
  paths = glob_runtimepath('snippets/**/*.json')
})
