How to get the workflow version?

[rullyalves]

In the documentation it says that I can get the workflow version with:
workflow.Version, but I checked the package and this function is not available

documentation link:

This is not supported:

Therefore for now versioning is not supported and the guidance is to rely on side-by-side deployments.

You pass in a version yourself as a parameter or you can use context propagation if you want this to be passed to sub-workflows etc.
