Hi guys, I'm trying Fleet and totally hyped with its' tremendous features. Especially, its MIT license and self-hosted part. Now, I wonder if I can develop some of the premium features myself (e.g., creating teams). I know that by purchasing the premium license, the premium features will appear immediately. But this is the case that I want to build some of the premium features by my own. Can you guys tell me if this is allowed? And is there any risk that I should not do this? Thank you
