Custom dimensions in GA4

Hello, I have been trying to get custom user scoped dimensions (User ID for example) from GA4 into Power BI but I have not successfully gotten the data into Windsor. I found a thread here from Jan 17 where you described how to call the values but I believe the answered referred to GUA. The layout has changed in GA4 and the index is no longer available. Is it possible to get these custom dimensions into Windsor still?
