Web push notifications support icon, image, and badge customization options.
Setting the Icon, Image, and Badge
You can add the default web icon in step 2 of the Web Push Setup configuration and step 5 of the Safari Web Push Setup in the Dashboard.
When Sending Push Messages, you can set the icon, image, and badge here:
Sending from API, use chrome_web_icon, chrome_web_image, and chrome_web_badge parameters
