powerbi - Power BI Gantt Chart - Tasks with 3 Hierarchy Levels and Monthly View

I use David’s Bacci Gantt chart via the pbix Deneb app available here

My data is a direct export from MS Project with 3 levels of task hierarchy that I want to include in the PBI visual. Now, I don’t consider myself a JS expert and I had a hard time making the necessary changes to work in the code.

Additionally, I’d like to get rid of the progress column for now (which has a red box overlaid above the column in the expected output image)

Here is an excerpt from the data
