"Extension" is missing from "Which type of client-side component to create?" when creating SPFx

Question

I am using Node.js 14.18.1 (x64) and npm.

When i run D:\extensionfullstack>yo @microsoft/sharepoint I got this :-

D:\>cd D:\extensionfullstack  
  
D:\extensionfullstack>yo @microsoft/sharepoint  
  
     _-----_     ╭──────────────────────────╮

Let's create a new SharePoint solution.  
? What is your solution name? extensionfullstack  
? Only SharePoint Online (latest) is supported.  For earlier versions of SharePoint (2016 and 2019) please use the 1.4.1  
 version of the generator. SharePoint Online only (latest)  
? Where do you want to place the files? Use the current folder  
? Do you want to allow the tenant admin the choice of being able to deploy the solution to all sites immediately without  
 running any feature deployment or adding apps in sites? Yes  
? Will the components in the solution require permissions to access web APIs that are unique and not shared with other c  
omponents in the tenant? Yes  
? Which type of client-side component to create?  
> WebPart  

Where "Extension" option is missing any advice? Thanks

Hi @john john ,
If you choose yes in Will the components in the solution require permissions to access web APIs that are unique and not shared with other components in the tenant?. It means you are creating isolated solution then make sure your solution have only webparts because it doesn’t work in extensions. As a workaround, please choose NO in this option if you want to create an extension
