How to do supertab in zed?

[TzeroOcne]

Is there a way to do supertab in zed? I mean use tab trigger completion, tab again to select next completion item, shit-tab to select previous completion item, and enter to confirm.

I've tried to do it with this keymap but tab keep doing confirm instead of select next

[
  {
    "context": "Picker > Editor",
    "use_key_equivalents": true,
    "bindings": {
      "tab": "menu::SelectNext",
      "shift-tab": "menu::SelectPrevious"
    }
  },
  {
    "context": "Picker || menu",
    "use_key_equivalents": true,
    "bindings": {
      "tab": "menu::SelectNext",
      "shift-tab": "menu::SelectPrevious"
    }
  },
  {
    "context": "(Editor && showing_completions)",
    "use_key_equivalents": true,
    "bindings": {
      "tab": "menu::SelectNext",
      "shift-tab": "menu::SelectPrevious"
    }
  }
]

In neovim I have this blink config for doing supertab

      ["<Tab>"] = {
        ---@param cmp blink.cmp.API
        ---@return boolean|nil
        function(cmp)
          local next_idx = (cmp.get_selected_item_idx() or 0) + 1
          local items = cmp.get_items()
          if next_idx > #items then
            next_idx = 0
          end
          local next_item = next_idx > 0 and items[next_idx]
          local next_source = next_item and next_item.source_name
          if cmp.is_menu_visible() then
            return require("blink.cmp").select_next({ auto_insert = highlight_map[next_source] and false })
          elseif cmp.snippet_active() then
            return cmp.snippet_forward()
          end
        end,
        "fallback",
      },
      ["<S-Tab>"] = {
        ---@param cmp blink.cmp.API
        ---@return boolean|nil
        function(cmp)
          local prev_idx = (cmp.get_selected_item_idx() or 0) - 1
          local items = cmp.get_items()
          local prev_item = prev_idx > 0 and items[prev_idx]
          local prev_source = prev_item and prev_item.source_name
          if cmp.is_menu_visible() then
            return require("blink.cmp").select_prev({ auto_insert = highlight_map[prev_source] and false })
          elseif cmp.snippet_active() then
            return cmp.snippet_backward()
          end
        end,
        "fallback",
      },
