Client side logging from browser without exposing keys

[foysalit]

Hello! I am trying to set up logging from the browser to logflare but all docs I could find point at configuring the pino logger instance with both apiKey and sourceToken in the browser. That can't be safe to expose to the world, right? What is the secure way of using the logger directly from the browser?

Following this documentation https://github.com/Logflare/pino-logflare/blob/master/docs/VERCEL.md BTW, fails on vercel because the client won't receive process.env.<ENV_VAR> unless those are public ones.
