What is a button you click to open the dialog box on Microsoft?

In Microsoft applications, the button that typically opens a dialog box is the "Dialog Box Launcher," which is often represented by a small arrow or square icon located in the bottom right corner of a group on the ribbon. Clicking this icon will bring up a dialog box related to that group, allowing for more detailed options and settings. Alternatively, you can often access dialog boxes by right-clicking on an item and selecting an option from the context menu.
