`assignedResources`	List<`ConnectApi.AssignedResourcesInput`>	Represents the service resources who are assigned to a service appointment.

For example, suppose that an existing service appointment has assigned resources: A and B and you pass B and C in assigned resources in the PATCH request. The API checks the resource availability of B and C for existing work type and service territory, and if both are available, the service appointment gets updated with: Resource A—Deleted ResourceB—Updated ResourceC—Created However, if you don’t pass any of the assigned resources, the API assumes there’s no change.
