How to generate GOOGLE_CLIENT_ID and GOOGLE_CLIENT_SECRET without a domain?

I would like to create a new Google API project for a nextJS webapp. I cannot understand how to get the API GOOGLE_CLIENT_ID and GOOGLE_CLIENT_SECRET without a domain.

I have to setup in the .env file

# Next Auth Google provider
GOOGLE_CLIENT_ID="XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX"
GOOGLE_CLIENT_SECRET="XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX"

I tried looking for solutions but I cannot find the resources.Screenshot showing the options
