I think the change should be use id of content library template to query vm template, not to query content library vm template then query vm template, which make fewer line changed and less query make
for example change

	gvtp.RequestBody = &models.GetVMTemplatesRequestBody{
		Where: &models.VMTemplateWhereInput{
			ID: &id,
		},
	}

to

	gvtp.RequestBody = &models.GetVMTemplatesRequestBody{
		Where: &models.VMTemplateWhereInput{
			ContentLibraryVMTemplate: &models.ContentLibraryVMTemplateWhereInput{
				ID: &id,
			},
		},
	}

also can add an extra First:1 or combined cluster where clause to query only one template, all template under same content library template should have common meta data
