Execute powershell script remotely on Amazon EC2 instance from my local computer

I have an Amazon EC2 instance.

Using powershell on my local workstation, I want to be able to remote into my Amazon EC2 instance and execute some commands.

I have found many articles online but none are working or I misunderstood them (probably the latter).

Some I tried are
Managing Windows EC2 Instances remotely with Powershell
Administering EC2 instance with Windows Powershell
Enabling- PSRemoting
How to Run PowerShell Commands on Remote Computers

My understanding is that I need to:

Amazon EC2 Dashboard > Network & Security > Security Groups > Add port 5985

//Local & EC2 PowerShell(Administrator)
enable-psremoting -force

//Local PowerShell(Administrator)
set-item wsman:\localhost\Client\TrustedHosts -value "*" -force

$password = convertto-securestring -asplaintext -force -string myPassword
$credential = new-object -typename system.management.automation.pscredential -argumentlist "myUsername", $password
$session = new-pssession ec2-00-00-00-000.compute-1.amazonaws.com -credential $credential
enter-pssession $session  

But I get this error

new-pssession : [ec2-00-00-00-000.compute-1.amazonaws.com] Connecting to remote server
ec2-00-00-00-000.compute-1.amazonaws.com failed with the following error message : WinRM cannot complete the
operation. Verify that the specified computer name is valid, that the computer is accessible over the network, and
that a firewall exception for the WinRM service is enabled and allows access from this computer. By default, the WinRM
firewall exception for public profiles limits access to remote computers within the same local subnet. For more
information, see the about_Remote_Troubleshooting Help topic.

How do I run a remote PowerShell script on a remote computer?

To run a script on one or many remote computers, use the FilePath parameter of the Invoke-Command cmdlet. The script must be on or accessible to your local computer. The results are returned to your local computer.

Solution found here.

The missing link was to (on the EC2 instance) open Windows Firewall with Advanced Security and edit an inbound rule.

Full Steps:

EC2 Instance
1) Open PowerShell as administrator
2) Enter enable-psremoting -force
3) Open Windows Firewall with Advanced Security
4) Inbound Rules -> Find Windows Remote Management (Http-In) - there are 2, do this for both
5) Right click -> Properties -> Advanced -> Check public

6) Open PowerShell as administrator
7) Enter enable-psremoting -force
8) Enter the following:

$password = convertto-securestring -asplaintext -force -string MY_PASSWORD  
$credential = new-object -typename system.management.automation.pscredential -argumentlist "MY_USERNAME", $password  
$session = new-pssession MY_EC2_PUBLIC_IP -credential $credential  
enter-pssession $session  
Write-Host "Hello, World (from $env:COMPUTERNAME)"
