You need to configure the environment to meet the technical requirements for guest users. What should you do to modify the Microsoft Teams admin center?

The global app permission policy controls which apps are available to users within Teams, not general access or capabilities for guest users.

Org-wide settings in the Microsoft Teams admin center include specific sections for "Guest access" and "External access," which are critical for controlling how guest users can interact with your Teams environment. These settings define general permissions, features, and capabilities available to guests across the organization.

The global meeting policy controls settings related to meetings for users, but general guest access permissions are broader than just meetings.

The global messaging policy controls chat and channel messaging features for users, not the overarching access and capabilities of guest users.
