Hello @danielmeza thank you very much for your PR.

It worked perfectly!

However, I decided to drop the usage of the static interop mode in favor of the new non-static/instance mode and that made me rewrite a lot of code and for that reason it made me not merge this and rather keep my changes.

Please don't see it as a means of judge badly your PR. The code was perfect, that changes worked, everything is fine. I just did that so I could easily unblock myself with the other changes.

Please feel free to submit any other PR you feel necessary and we will evaluate it.

Again, thank you very much for your time! I hope to see other contributions from you soon!
