What is the proper information of the extension for the variable VSCODE_EXTENSION_IDS

[Wizard]

In here it says I can install vscode extensions. It even gives the following examples:

For example, to install the vscode-docker and vscode-icons extensions add the following lines to your docker compose service:
VSCODE_EXTENSION_IDS: ‘vscode-icons-team.vscode-icons|ms-azuretools.vscode-docker’

The problem is that I can see that the name of the extension vscode-docker it appears to map to ms-azuretools.vscode-docker and I am left lost how could I know the name I need to give it to install an extension named coderoad. I cannot find any code extension id for it.
Can anyone help me to understand how you can find out the entry expected for extensions?

I think I found the how. I searched for the example extension and I finally saw at the lower bottom some information that matches the example given.
