To ensure that users in the Green group can access the Help Desk app upon login, editing the group start page in User Start Pages is the necessary action. This feature allows administrators to customize the initial experience for users based on their group associations. By modifying the start page specifically for the Green group, you can direct these users straight to the Help Desk app as soon as they log in, optimizing their workflow and ensuring they have immediate access to the resources they need.

The other choices are not relevant to achieving this specific requirement. Assigning users to a different group does not address the need for the existing Green group to access the Help Desk app; it simply changes their group affiliation. Changing login credentials is unrelated to the app access requirement and does not facilitate direct navigation to the Help Desk app. Updating user profiles may modify user information but does not inherently provide or improve access to the Help Desk app. Thus, customizing the group start page is the most effective and direct solution in this scenario.
