How to add jump node to the end of each snippet

[aShabat]

Hello. I'm trying to add ability to jump to the end of each snippet. I can add this to my snippets, but I want to also be able to do this with lsp snippets. I wrote autocmd

vim.api.nvim_create_autocmd("User", {
    pattern = "LuasnipPreExpand",
    --once = true,
    callback = function()
        local snippet = require("luasnip").session.event_node
        local docstring = snippet:get_docstring()
        if not docstring[#docstring]:match('%$0$') then
            local luasnip = require'luasnip'
            local s = luasnip.s
            local i = luasnip.i
            local t = luasnip.t
            luasnip.snip_expand(
                s('surrounding snippet', {t("", ""), i(0)})
            )
        end
    end
})

but it adds empty snippet after the one that triggered the event. This works if i have link_roots = true in config, but i would prefer to disable it. Also this doesn't work without the text node, but I assume that it's because it becomes nothing-snippet.

Is there some other way to achieve this?
