TIWBSButton Glyphicon

[Comograma]

On Bootstrap 3, the TIWBSButton had a property BSGlyphicon to add an icon to the button.
On Bootstrap 4 component TIWBS4Button, this property do not exist.
How can I add an icon to the button? Is this possible like as for the component of Bootstrap 3 to do the same with Bootstrap 4 component?
