To successfully implement the Salesforce Grants Management package and an accompanying portal, specific prerequisites must be met. The Grants Management application is built exclusively for the Lightning Experience, necessitating the migration of internal users from Salesforce Classic. Chatter is a core requirement for the application's collaborative features and record feeds to function correctly. For the external portal, where grant applicants will manage their applications, Customer Community Plus licenses are required. These licenses provide the necessary object access and advanced sharing capabilities for grantseekers to interact with their specific funding request records within the portal.

A. Customer Community Licenses: This license type is insufficient. The Grants Management portal requires the advanced sharing and object access capabilities provided by the Customer Community Plus license to function as designed.

C. Enable Web-to-Lead: This feature is used for capturing marketing leads from a website into the Lead object. The Grants Management intake process uses a dedicated portal and custom objects, not the standard Web-to-Lead functionality.
