Question is asking about solution not a feature. Workflows can be created in the VRA to automate certain tasks and actions.

For an end-user enablement, vRealize Orchestrator Plug-in for Horizon integrates with vRealize Automation to provide self-service access to applications and desktops. The plug-in workflows can be integrated with the request and approval processes that are built into the vRealize Automation service catalog, allowing end users to refresh their own desktops. End users can make requests that follow a standardized and auditable process that can result in immediate action, or they can direct their requests for administrative approval. For desktop environments where virtual machines must support rapid change and reuse, end users can provision desktops for themselves and de-provision, or recycle, the desktops to reduce waste of resources and capacity.

C vRealize Orchestrator Plug-in for Horizon provides automation, self-service, and delegated administration for VMware Horizon 8 environments. End users can perform self-service functions. Delegated administrators can perform provisioning functions on behalf of end users. https://docs.vmware.com/en/VMware-Horizon/2212/using-vro-plugin-for-horizon/GUID-1A4E3323-7D3B-44DD-871F-2579A863EE5C.html

The administrator can use VMware vRealize Automation (Option C) to meet this requirement. vRealize Automation is a cloud management platform that enables organizations to automate the deployment and management of IT resources, including virtual desktops and applications. In the scenario described, vRealize Automation's Self-Service capabilities could be used to allow managers to request desktops for their employees. The administrator could create a self-service portal where managers could log in and request desktops, specifying the applications and configurations they require. The administrator could also set up approval workflows to ensure that requests are reviewed and approved before the desktops are provisioned. vRealize Automation also provides robust management and automation capabilities, enabling the administrator to automate the provisioning and configuration of desktops, as well as manage changes to the desktops over time. This could help to streamline the desktop management process, reducing the time and effort required to manage and update desktops, and improving overall efficiency.
