Reference Azure Data Lake Path directly in Azure Fabric Notebook using Workspace Identity.

Hi anawast 
Thanks for using Fabric Community.
Currently, directly referencing an ADLS Gen2 path with workspace identity in a Fabric notebook using spark.read.format("delta").load("abfss_path") isn't supported. 

However, your suggestion is definitely valuable! We use customer feedback like yours to prioritize future features. The more users who request the ability to customize backgrounds, the higher it moves on our list.

Appreciate if you could share the feedback on our Microsoft Fabric Ideas. Which would be open for the user community to upvote & comment on. This allows our product teams to effectively prioritize your request against our existing feature backlog and gives insight into the potential impact of implementing the suggested feature.

I hope this information helps. If you have any further queries please do let us know.

Thanks
