How are we jumping around in snippets?

[windowsrefund]

Hello. Thank you for this repo. As a result, I have some really sweet bindings set for the purpose of handling completion. However, I've been unable to setup my Tab and S-Tab bindings so they can be used exclusively to jump around between snippet placeholders. Adding the contents of my after/plugin/lsp.lua here in the hopes someone might shed some light. Thanks in advance.

local lsp = require("lsp-zero")

lsp.preset("recommended")


lsp.ensure_installed({
	'pyright',
	'bashls',
	'yamlls',
	'sumneko_lua',
})

lsp.nvim_workspace()

local cmp = require('cmp')
local luasnip = require("luasnip")
local cmp_select = {behavior = cmp.SelectBehavior.Select}

local cmp_mappings = lsp.defaults.cmp_mappings({
	['<C-k>'] = cmp.mapping.select_prev_item(cmp_select),
	['<C-j>'] = cmp.mapping.select_next_item(cmp_select),
	['<C-y>'] = cmp.config.disable,
	['<C-e>'] = cmp.config.disable,
	-- toggle completion
	['<C-l>'] = cmp.mapping(function()
		if cmp.visible() then
			cmp.abort()
		else
			cmp.complete()
		end
	end),
	-- navigate snippet placeholders
	['<Tab>'] = cmp.mapping(function(fallback)
		if luasnip.jumpable(1) then
			luasnip.jump(1)
		else
			fallback()
		end
	end, { "i", "s" }),
	['<S-Tab>'] = cmp.mapping(function(fallback)
		if luasnip.jumpable(-1) then
			luasnip.jump(-1)
		else
			fallback()
		end
	end, { "i", "s" }),
})

	mapping = cmp_mappings

https://github.com/anon-marvin/Neovim/blob/main/after/plugin/lsp.lua , Compare ur config and mine , u have to add few lines of code to make it work
