YouTube OAuth Scope Approval Assistance

I’ve built a web-based platform that relies on the YouTube Data API v3 in readonly mode. Before launching publicly I need the OAuth consent screen verified by Google so users can grant that specific scope without the unverified-app warning.

My project is already running in Google Cloud Console; OAuth client credentials and the consent screen are set up, but I have not yet begun the formal verification process. I want an expert who has taken a Web application through Google’s external verification—specifically for the youtube.readonly scope—to walk me through (or directly handle) everything Google requires: branding assets, privacy policy wording, domain ownership proofs, and the security-assessment questionnaire.

Deliverables
• A fully approved OAuth consent screen for the youtube.readonly scope
• Clear documentation of each step taken so I can replicate it in future projects
• Short hand-off call or screencast demonstrating the live, verified flow

Acceptance criteria: the application passes Google’s review, users no longer see the unverified warning, and the YouTube Data API calls succeed in production with live user tokens.
