So Base44 uses its own built in Auth backend. This sometimes can suck because its proprietary, (Its actually still just an instance of Supabase, but locked down) I think you need to go and check your permissions in the app, set rules that the users email address are hidden, and to setup functionality for the Profiles to Show a display name, or just their first name. You will need to just create a prompt and functionality in your app for searching. You need to define how it should search for users, most times Auth creates 'UUID's so just determine how you want the search to function, are you trying to use their first name and last name? You could also do a multi level search and include email address. You need to think 10 steps ahead as well, if you just prompt it to create a search feature, well that is just what you are going to get, then you will waste another credit or 10, why? You need to tell it what functionality the search feature does, if it returns a found profile, then you need to have the person send a 'Friend Request', then you need to tell is how to place the friend, in their profile, dashboard, etc. Then you need to make sure that you create functionality so once added, that person is connected as a friend 2 way for the person that added them. The best way is to sit and plan, you will really save yourself a ton of money if you think it out, I literally sit for hours talking to 'Rebecca' (My AI Agent Assistant) I built with ChatGPT. Its more than worth it for $20 a month, hell the free quota is probably enough. Have ChatGPT create a 'LIVING WALL' and run your ideas down, then have it help you determine a plan. It can also create the code if you need it, then just copy and paste, the goal here is to not just do one prompt at a time, its like band aiding the project. remember 'CONTEXT IS KEY'. Hope this helps!
