How to add an icon to a button?

To add an icon to a button, open the Content panel of the block with the button and find the button text field. In this field, click the button on the left. When you hover over it, the select icon tooltip appears.

You can choose an arrow, use a ready-made icon from one of the available icon libraries, add an emoji, or upload your own file.

The editor also lets you set a separate icon that appears when a visitor hovers over the button.
