You're a Workspace Owner and App Manager for your company's Slack Enterprise Grid instance.

Slack’s app management guidelines advise:

"Before approving an app, you should review its compliance with your organization's data security policies and understand which external services and APIs the app communicates with."

Availability in the Slack App Directory (A) doesn’t guarantee security compliance. Whether the app connects with your HR system (D) is helpful but not a core initial security evaluation criterion.
