I just checked and agree with you, i think these functions are missing.
Of course you could disable this new UI and just use the old one.
Maybe create a support ticket or post this on the idea forum.
Either they want to abandon labels, which I do find a wrong decision. Or the missed it in the new UI, which is kind of silly.
Anyhow, pretty annoying. Since Mendix removed the feedback button from their own platform, providing feedback is a harder to do. Only option I do see it to put it in the #mx-user-research slack channel.

The new look is indeed missing those functions. The only option, is switching back to the previous layout
