Hai everyone!!
My name is Niko Prianto. I’m a junior UIUX designer from Indonesia who currently working for a company with highly confidential projects. I’ve been using figma for almost 3 years now and what a delight experiences for our work 
But my team recently discovered that our work of design can be copied and edited by Viewers to their own created file. We were worried that some of our viewer-users can alternate and disrupt our design process, extending designs using our work as a base. I know figma has a feature to turn this off, but if we do that it may restrict our developers access from exporting icons, layers and stuff.
Any tips on this particular case? Thanks in advance
