How to do VSCode remote connection to EC2 via EC2 Instance Connect (EIC)?

Hello.

If you use VSCode's RemoteSSH extension, try setting ssh_config as follows.
"ssh.pem" is the SSH key set to ec2-user.
With this setting, you will be able to connect to EC2 configured with ProxyCommand and manipulate files.

Host instance1
    HostName i-0eyyyyyyyyyyy
    User ec2-user
    IdentityFile .\Desktop\tmp\ssh.pem
    ProxyCommand aws ec2-instance-connect open-tunnel --instance-id i-0eyyyyyyyyyyy
