Control Type?

In Big Sur, if you open the “About This Mac” window, there are what looks like buttons built in to the title bar.

What controls are they, and is is possible to put them in the title bar natively in the latest Xojo release?

Thank you all in advance.

That is the new style for Windows with Toolbar in the window title.

Thanks, so is this possible to do natively in Xojo, or are plugins required?
