I have created an TinyMCE Editor (in admin only) button which appears in editor toolbar fine and functioning properly. Right now the button says “Live Chat”, what I want to replace with a dashicon or a font awesome icon.
I have the following code in my plugin.js file:
ed.addButton('livechat', {
text: 'Live Chat',
icon: 'dashicons dashicons-admin-links',
tooltip: 'Live Chat',
cmd: 'livechatButtonCmd',
});
Instead of showing a dashicon, it is showing a small empty rectangle. What is the correct way of doing this?
