I've just integrated AviarySDK on a game that will allow editing a puzzle solution image. Everything's working fine, but I've realized that there's a login / register button on the NavigationBar.-
I'd rather not letting users to log in, as the game itself has its own login / register workflow and this might confuse them. Is there any way to hide or disable this button on iOS and Android sdk?

The login lets users manage their Image Editor content (filters, stickers, frames, etc) across devices and apps with Creative SDK Image Editor integrations.
It's possible to remove the login button by removing all content tools from the Image Editor. When all content tools are removed, the user login will go away.
iOS
You can do this with the
setToolOrder:method:Details in the Image Editor guide for iOS.
Android
You can do this with the
withToolList(ToolLoaderFactory.Tools[])method:Details in the Image Editor guide for Android.
Note: Tools in the arrays are inclusive; those omitted from the array will not appear in the Image Editor. The order of the tools in the array is respected in the UI.
