New project not showing on firebase CLI

There is a simpler solution, first, determine your projectId from the Firebase Console. Firebase usually adds a random number to your project's name i.e if you are using demo as the project name the projectId will look like demo-1234

Next, in your terminal, cd into your project's target directory and issue the followoing command

firebase -P <projectId> init

assuming demo-1234 was my projectId, I will issue the command as below

firebase -P demo-1234 init

Use firebase use --add projectId, this will add your project
