About costumizing bar

Hello,
I need to know where I can fiind file to disable same option of the bar to remove emoji and other option on this.
Is possible to enable same option only to registerd user?

Welcome to the forum.

You can specify which buttons you want to show on the toolbar in your config.js. If you want to control which buttons are visible based on role, you should look into using iFrame.

Need create a bar on bottom without emoji and in more action remove background option.
now try to see more info about Iframe.
