How do I reload LuaSnip so that my snippets are updated?

[UtkarshVerma]

I noticed that lazy has the Lazy reload command which I can use to reload a plugin. I have the following spec for LuaSnip in my config:

---@class plugins.luasnip.config
---@field region_check_events? string
---@field delete_check_events? string
---@field update_events? string[]

---@type LazyPluginSpec[]
return {
  {
    "L3MON4D3/LuaSnip",
    build = "echo 'NOTE: jsregexp is optional, so not a big deal if it fails to build'; make install_jsregexp",
    ---@type plugins.luasnip.config
    opts = {
      region_check_events = "CursorHold,CursorMoved,InsertEnter",
      delete_check_events = "TextChanged,InsertLeave",

      -- For dynamic snippets.
      update_events = { "TextChanged", "TextChangedI" },
    },
    config = function(_, opts)
      local luasnip = require("luasnip")
      luasnip.setup(opts)

      luasnip.add_snippets("all", {
        luasnip.parser.parse_snippet("expand", "-- this was expanded as"),
      })
    end,
  },
}

What I want is, if I define a new snippet in luasnip.add_snippets(), reloading via Lazy reload LuaSnip should allow me to use the newly created snippets. However, I have not been able to do so.

Could someone please let me know what I might be doing wrong?
