What is the correct application type for CommerceProxyGenerator to generate for POS

[RethaLam]

I used to use on RetailSDK TypeScriptProxy.Extensions to generate the DataServiceEntities.g.ts and DataServicReauest.g.ts for me.

I would like to use it for CommerceSDK as well.
I set up my project according to https://github.com/microsoft/Dynamics365Commerce.ScaleUnit/blob/release/9.47/src/ScaleUnitSample/CommerceProxyGenerator/TypeScript/TypeScriptProxyGenerator.csproj.

However it doesn't generate anything for TypeScript. If I change the CommerceProxyGeneratorApplicationType to TypeScriptModuleExtensions for e-Commerce, then it generates it.

so something tells me that the CommerceProxyGeneratorApplicationType provided for POS is incorrect. The documentation states to use typescriptextensions. I can leave it all small letters or change it to TypeScriptExtensions, still nothing.

So can somebody please let me know what is the correct application type to use if I want it generated for POS?
