camsoda chat

I've been working on Camsoda for about 3-4 months now d have figured everything out besides how to clear my chat history like I see other girls doing on their page

Hi, I'm a viewer and moderator of some girls and while on Chaturbate I'm able to upload a variety of GIFs/Images custom made to "my models" in Camsoda I'm not finding how to do it if there's a way at all to do it. So, anybody more used to the site can gimme some information about it? Thanks in...
