how to use tab for both select_next snippet_forward based on condition.

[shaeinst]

in simple term what would be the blink.cmp version of this nvim-cmp

	local cmp = require("cmp")
	local luasnip = require("luasnip")
	local neotab = require("neotab")

			["<Tab>"] = cmp.mapping(function(fallback)
				if cmp.visible() then
					cmp.select_next_item()
				elseif luasnip.expand_or_jumpable() then
					luasnip.expand_or_jump()
					-- this will auto complete if our cursor in next to a word and we press tab
					-- elseif has_words_before() then
					--     cmp.complete()
				else
					neotab.tabout()
					-- fallback()
				end
			end, { "i", "s" }),

			["<S-Tab>"] = cmp.mapping(function(fallback)
				if cmp.visible() then
					cmp.select_prev_item()
				elseif luasnip.jumpable(-1) then
					luasnip.jump(-1)
				else
					fallback()
				end
			end, { "i", "s" }),
