Hi folks! I'm using the Fastly CDN tool to create a GCS-backed service. Everything works great, aside from one piece: adding a VCL Snippet. (Fastly recommends this in their by-hand instructions.) I want to create a new https://www.pulumi.com/registry/packages/fastly/api-docs/servicedynamicsnippetcontentv1/#inputs --but it looks like I need a snippet ID of an existing snippet to create a new one. Chicken/Egg? Do you folks have some ideas?

fixCachingVCL, err := fastly.NewServiceDynamicSnippetContentv1(ctx, "X-Http-Method-Override",
	&fastly.ServiceDynamicSnippetContentv1Args{
		Content:   pulumi.String("unset req.http.X-Http-Method-Override;"),
		ServiceId: bitmovincdn.ID(),
		SnippetId: , // Need a real one. manual?
	})
