RichTextEditor - how to hide some options?

Hi, all!

Something about hiding of toolbar options I found information on forums. Must to make html-module and include this in java object by setting custom id of this module as I understand, but anyway not fully understand how to do this in project… I just want hide image upload in text editor, can someone explain how to do this correctly in Vaadin 13 or give nicely source with step by step instructions.

Thanks.
