Is there an equivalent of AcquireTokenByUsernamePassword in .NET Framework 4.6.1? I am trying to implement ROPC flow to AD B2C "local" user account, but the docs for this class say that it's only applicable for .NET Core. Although, it does let me use it in the code, but it doesn't work. I followed all of the instructions, but still getting permission errors. I am wondering if it's my setup issues or the framework.
Unfortunately, we are stuck with the old framework for now.
