- Get All Gmail Labels (Gmail): work with label
- Filter User Labels (If): checks a condition and branches into true / false

Services it uses
Before you upgrade to n8n 3.0
1 thing in this workflow is removed in n8n 3.0. Fix it before you upgrade:
- Function (legacy) in Get Specific File Types, Get All Attachments: replace with Code node, mode 'Run Once for All Items'.
- Also check Gmail Trigger below v1.4 runs as v1.4 (drafts skipped, max emails per poll).
Rather not rewrite it? Many of these flows can be rebuilt in Make (free plan).
