There are different types of buttons:

• Hotspot (Empty button)

• Solid Color

• Flat

• Raised

• Floating action button

• Borderless icon

All of these can be selected in the Elements tool bar.

The settings of the button can be changed individually in the Element inspector.

There are many pre-installed icons. However, there is always the options to upload an SVG-file in case an icon is missing.
