How can a Project Manager help a user receive a confirmation when entering a request?

The correct choice highlights the specific actions a user can take regarding their own request notifications. By addressing the user's notification settings for requests they enter, the Project Manager effectively guides them to ensure they receive confirmations tailored to their submitted requests. This focused support empowers the user to manage their expectations and communication regarding the requests they submit, improving their overall experience with the platform.

In the context of the other options, changing notification settings for projects they own or for actions needed might not directly relate to the user's immediate concern about confirmation for their specific requests. Similarly, directing a user to find general project notification details does not empower them to manage their personal notifications about their request submissions effectively.
