CloudFormation support for InstanceConnectEndpoint

Question

Even though `AWS::EC2::InstanceConnectEndpoint` seems to have been added to CloudFormation docs on June 15 [1], I get the following error in more than one region that I've tried:

```
Template format error: Unrecognized resource types: [AWS::EC2::InstanceConnectEndpoint]
```
Is it normal for a new service to have appeared in CloudFormation docs but not work for a while, or are the docs on this particular resource [2] not accurate?

AWS seem to have deleted the `AWS::EC2::InstanceConnectEndpoint` line from CloudFormation Release Notes!

I have tried us-east-1, us-west-1 and eu-west-2. The instance endpoint, when provisioned through the web console, works perfectly fine. Just the CloudFormation issue persists.

Strange that they'd add it to CloudFormation docs when CloudFormation doesn't support it yet.

Hello Wanderer,

Not normal but possible. Could find a similar Twitter post on other resource type: https://twitter.com/sshvetsov/status/1370641664260239362?lang=en

Have you tried in which region?

The supported endpoints are https://docs.aws.amazon.com/general/latest/gr/ec2-instance-connect.html

From experience I see support is first added to us-east-1, eu-west-1 and ap-southeast-1 then rolled out to other regions, maybe trying launching it in us-east-1 to confirm the doubt? Thanks!
