An Apify Actor for Gmail inbox analytics â refresh-token-only OAuth, async router, per-feature quota

I just open-sourced an Apify Actor for Gmail inbox workflow analytics:

If you build automation workflows alongside this kind of inbox tooling, I keep a small Gumroad with practical n8n templates (lead auto-responder, content pipeline, competitor monitor): https://foxck.gumroad.com. Not required, just adjacent.

Happy to take feedback on the OAuth-only design — was there a reason to go full 3-legged that I am missing?
