How do find the user/principal submitting my Spark Application?

I've been trying to track down why I can't submit an application/run a Synapse Notebook, but some guid can. In the monitor section of Azure Synapse Workspace. I click on Apache Spark Applications and I see a column for submitter. I see my username which fails, but I also see a submitted described as a guid. How do I figure out the service principal/user associated with this guid? Also how specify which user should be used to submit an application when I run a notebook via a pipeline? Currently all pipelines submit applications using a default guid.
