Sync for Lemmy

I feel like I'm going insane, I can see people talking about logging in. I have seen screenshots of the login screen. And when I attempt to submit a post or something it tells me I need to be logged in to do that. But I cannot for the life of me no matter how hard I search the settings find somewhere to log in. I have tried searching for account, login, profile in the settings search and found nothing I have manually gone through every single category and cannot find anywhere to log in. I have attempted to completely uninstall and reinstall the application. This is either the most elaborate gaslighting attempt against some random asshole in history or there is something wrong with my app
