envato theme plugins cant apperar in wordpress dashboard

after activating envato theme package, plugins that provided by envate cant work, they not appear in wordpress dashboard after activation

What theme/plugins is this?

Was it from themeforest or envato elements?

Do they literally not appear or just ask for activation?
