fb_scr_izan collector

Collects group posts from your own logged-in Facebook session and sends them to your local workspace.

Where fb_scr_izan is running.
From the workspace: Group Posts → collector token. This authenticates the extension to your workspace. It is not a Facebook credential.
What this extension does not do. It never reads, stores or transmits your Facebook password, cookies or session tokens. It reads the bodies of GraphQL responses your browser already receives, and sends only parsed post records to the local workspace address above.
