How can i make it be an icon instead of a text. Look at the picture. I have tried to do my own CSS but it always just comes back as a send text button. I was able to get the icon the the webstyler but when i generated a link and pasted it over it didn't change. Is it simply just not possible?

Are you using the pre-configured code or the configurable code? Pre-configured code takes some time to update the styles.

Inside your CSS file you can configure how the send button looks and add a background image. https://botpress.com/docs/cloud/webchat-customization/user-input/
