Accessing AWS Cloud Map from a Lambda in a VPC

Well that's pretty annoying. Any plans/timeline if a VPC endpoint would be added for cloudmap?

If you have a resource in a VPC (Lambda, EC2 instance, Workspaces, etc.) that needs access to the internet (in this case to an API endpoint but really, anything) from a private subnet then you'll either need to use NAT (NAT Gateway, your own NAT instance) or a proxy server (self-managed) - but either solution is pretty much doing the same thing.
