Downgrade .NET 6 API to .NET Core 3

Question

I cannot create a .NET Core 3 application using Visual Studio 2022. It is only showing .NET 6 and 7.

I want to publish this API on IIS server, which does not support .NET 6.

I tried to change the project version from in the properties or in the csproj file, but it causes errors.
