Issue with accessing helpers and protos internal package while creating new backend for oracle database

[umeshdkonda]

Hi,
I am trying to create a new backend implementation for using Oracle database. I am implementing the methods present in the Backend interface and also using the SQLite implementation as a reference. However, I am facing issue while importing the "Helpers" and "Protos" packages are they are under internal folder. Below is the error that I see

"could not import github.com/microsoft/durabletask-go/internal/helpers (invalid use of internal package "github.com/microsoft/durabletask-go/internal/helpers")compilerBrokenImport"

Is there any way that I can use these packages for implementing Oracle backend?

Thanks,
