What instance resource allows you to access guided tours, information about actions, and instructions on how to use inputs and outputs in your flow?

Docs (docs.servicenow.com) is the official external documentation portal, not an in-instance help resource.

Community is an external forum for user discussions and support, not a built-in help panel.

The Help Panel, identified by a question mark icon, is an in-instance resource that provides contextual assistance, guided tours, and detailed information about features, actions, inputs, and outputs directly within the ServiceNow environment, such as in Flow Designer.

Wiki refers to an older, external ServiceNow documentation platform, now largely replaced by the official documentation site.
